Abstract:
Abstract Recently, largely deformed simulation models, such as car crash simulations, have been in high demand. To evaluate such models, it is necessary to use actual deformation results to compare and validate them. When measuring actual deformed objects, an X-ray CT is useful because it is non-destructive. However, matching undeformed CAD data and scanned deformation data is difficult. We propose a system for users to set control points or control lines on feature points and predict deformation using affine transformation with the moving least squares method. In the proposed method, undesirable distortions are reduced by evaluating scaling using singular value index and introducing offset control points. The deformed CAD data are obtained by matching predicted CAD data and a polygon mesh generated by deformed CT data. In addition, the surface elements of the generated deformed CAD data are evaluated for CAE.

Abstract This paper details the numerical modeling of composite absorbers and an assessment of the influence of such deformation elements on a bus during frontal collision with a car. The absorber itself is designed as an assembly of thin-walled composite wound tubes oriented in the vehicle direction of travel. During the impact the tubes are crushed, causing energy absorption. Crash simulations were performed at various speeds using differing scenarios with the deformational member as well as without it. Comparative diagrams of force and velocity of the car and deformation of the bus structure were assessed

Abstract:
Expertise on the materials of road accidents (road accidents), calculate the speed of the vehicles involved in the accident by analyzing the resulting deformation damage by the average stiffness coefficients of the vehicle bodies. But this entails the presence of an error in the calculation and, as a result, not a correct result due to the fact that the internal structure of the side of the car is heterogeneous – the stiffness in each of its areas is different. To eliminate possible errors when using the averaged coefficients, the article offers a method for calculating the stiffness coefficients for various areas of the side of cars that have received deformations as a result of an accident.

Abstract:
Les joints de porte et de vitrage des voitures jouent un rôle très important dans la réduction du bruit d’origine aérodynamique, à la fois par transmission directe et de par son rôle en tant que condition limite ees autres éléments transmetteurs (portes et fenêtres). Par conséquent, sa conception est fondamentale pour l’optimisation du confort de passager. Néanmoins, la méthode traditionnelle pour sa conception, basée sur une approche par tâtonnement de tests en soufflerie, est très coûteuse et insuffisante. Une approche différente est envisagée dans ce manuscrit, par la création d’un modèle capable de prédire la transmission du bruit jusqu’`a la cavité du véhicule, qui puisse être appliqué ultérieurement dans une routine d’optimisation. La modélisation des joints de vitrage et des fenêtres fait face à plusieurs difficultés. La fermeture de la porte subie par le joint de porte avant d’être soumis à l’excitation acoustique, ainsi que le comportement hyperélastique du caoutchouc, mènent à des déformations non-linéaires. Ce comportement change les propriétés (telles que la rigidité) du joint comprimé lors qu’il est soumis à l’excitation acoustique. De plus, l’interaction du son transmis par les joints avec la cavité du véhicule doit être prise en compte. Néanmoins, la taille réduite et la géométrie complexe du joint appellent à une approche telle que la méthode EF, tandis que la grande taille de la cavité véhicule nécessite d’une approche plus grossière, pour ne pas aboutir sur un modèle trop lourd. La solution proposée dans ce manuscrit implique la création d’un modèle hybride capable de modéliser le joint et la cavité séparément, avec l’approche la plus adaptée `a chaque cas, et de les coupler dans un seul modèle. Les comportements hyperélastique et viscoélastique des joints, avant et durant l’excitation acoustique, sont modélisés à l’aide du code commercial ABAQUS, tandis qu’une méthode énergétique appelée Méthode Energétique Simplifiée est utilisée pour la propagation ´ du son depuis les joints jusqu’au reste de la cavité. Cette méthode, adaptée aux besoins de l’application souhaitée, et couplée aux résultats du modèle EF, permet l’obtention rapide et locale du niveau de pression acoustique en n’importe quel point de la cavité. Finalement, des campagnes expérimentales sont mises en œuvre pour la validation des modèles. Les mises en place et les résultats sont détaillés dans ce manuscrit
Car door and window seals have been proven to be of utmost importance to reduce aerodynamic noise, both through direct transmission and through their role as boundary conditions of the other transmitting elements (car doors and windows). As consequence, their design has become of great relevance when it comes to passenger comfort optimization. However, the traditional method for their conception, based on a trial and error approach through wind-tunnel testing, has been found to be insufficient and costly. A different approach is contemplated in this dissertation, through the development of a model capable of predicting sound transmission through seals and into the vehicle cavity, for its subsequent application into an optimization procedure. Several difficulties arise from the modeling of car door and window seals. Indeed, the door closure imposed on the door seal before any acoustic excitation, as well as the hyperelasticity of the rubber lead to a non-linear deformation behavior. This behavior changes the seal properties (e.g. stiffness) which have to be modeled under acoustic excitation. Additionally, the interaction of the transmitted sound with the vehicle cavity must be taken into account. However, the small, precise geometry of the seal would call for an approach such as FE method, whereas the big dimensions of a vehicle cavity demand a much coarser approach so that the problem doesn’t become unmanageable in size. The solution that is proposed in this dissertation, implies the creation of an hybrid model capable of modeling the seal and the vehicle cavity separately, with the most adequate approach to each case, and coupling them afterward into a single model. As consequence, the hyperelastic and viscoelastic behaviors of the seals, prior to and during the acoustic excitation, are modeled through FE software ABAQUS, whereas an energy method called Méthode Energétique Simplifiée is used for the propagation ´ of the sound from the seal to the rest of the cavity. This method, improved to better suit the requirements of the discussed application, and coupled to the results of the FE model, allows a fast and local computation of the sound pressure level at any point inside the cavity. Finally, some experimental tests are put in place for the validation of the models. The different setups and results are detailed in this dissertation

Abstract:
The aim of this work is to assess the possibilities of using numerical simulation tools in the process of laser welding of the guide rail of a car seat. In the diploma thesis, a description of the components and the problem, which consists in the deformation of the groove of the guide rail, was made. A description was made of the manufacturing operations that the components go through. The positives of selected welding methods were evaluated and the choice of those used in production was justified. A description of the issues of laser welding, deformation and the use of simulation tools was made. The influence of individual production operations was evaluated in terms of the size and nature of deformations. Using the Visual – Mesh, Visual – Weld and Visual – Assembly simulation tools, which are products of the French company ESI Group, the same state of the simulated and real process was achieved. Subsequently, a proposal for the elimination of deformations and its verification using a simulation tool could be approached. The use of a spacer wedge, which acts on the most deformed places of the groove, was proposed. By its application, the resulting deformations were eliminated or significantly reduced. In the last part of the work, a technical and economic evaluation was made, taking into account the current global crisis and the important role of the automotive industry.

Simulation of a passenger car brake system, focusing on the prediction of brake pedal force and displacement based on the system components and their design characteristics."

Abstract:
This thesis presents an investigation of braking system characteristics, brake system performance and brake system component design parameters that influence brake pedal force / displacement characteristics as ‘felt’ by the driver in a passenger car. It includes detailed studies of individual brake system component design parameters, operation, and the linear and nonlinear characteristics of internal components through experimental study and simulation modelling. The prediction of brake pedal ‘feel’ in brake system simulation has been achieved using the simulation modelling package AMESim. Each individual brake system component was modelled individually before combining them into the whole brake system in order to identify the parameters and the internal components characteristics that influence the brake pedal ‘feel’. The simulation predictions were validated by experimentally measured data and demonstrated the accuracy of simulation modelling. Axisymmetric Finite Element Analysis (using the ABAQUS software) was used to predict the behaviour of nonlinear elastomeric internal components such as the piston seal and the booster reaction disc which was then included in the AMESim simulation model. The seal model FEA highlighted the effects of master cylinder and caliper seal deformation on the brake pedal ‘feel’. The characteristics of the brake booster reaction disc were predicted by the FEA and AMESim simulation modelling and these results highlighted the importance of the nonlinear material characteristics, and their potential contribution to brake pedal ‘feel’ improvement. A full brake system simulation model was designed, prepared, and used to predict brake system performance and to design a system with better brake pedal ‘feel’. Each of the brake system component design parameters was validated to ensure that the braking system performance was accurately predicted. The critical parameter of brake booster air valve spring stiffness was identified to improve the brake ‘pedal ‘feel’. This research has contributed to the advancement of automotive engineering by providing a method for brake system engineers to design a braking system with improved pedal ‘feel’. The simulation model can be used in the future to provide an accurate prediction of brake system performance at the design stage thereby saving time and cost.

The thesis deals with the issue of suspension of the 5th passenger car door. The introductory part deals with the possibilities of mounting the 5th passenger car door. In the next part, a HDS hinge was selected, which is further solved using a numerical and experimental method. Aluminium alloy was used on this HDS hinge to reduce weight. In the first step, a technical experiment was performed on the existing state (steel) and a strain-strain analysis was performed. Based on the stress-strain analysis of the material change variant without structural change, unsatisfactory results were obtained. After that, design changes were proposed such as increasing the thickness of the tube wall in the Creo program, and this variant was also subjected to a stress-strain analysis using the numerical modelling. Comparison of the results was based on the values of elastic deformation and equivalent stress. Finally, the thesis dealt with the manufacturability of the proposed component within which, a technical experiment was carried out.

Abstract:
The purpose of this study is to find the design tool to create a soft tissue 3D model able to be used for finite element analysis to simulate the facial soft tissue deformation under g-loading and the helmet and mask/tissue interaction. Such a model will be of value in the design of new helmets and oxygen mask system, to reduce the effects of inertia, to provide improved fit, to minimise oxygen leakage especially when deformed under high g-loading. This work is concerned with the creation of a 3D geometric model. Further work may involve the measurement of mechanical properties of the facial soft tissue, finite element analysis and validation of the model. Using high frequency A-scan ultrasound allows the superficial tissue to be measured on volunteers without risk. The investigation covers 112 points on half of the face, linked to 11 defined morphological zones. The zonal boundaries are based on previous research and are initially identified by inspection and palpation of the face. There is large thickness range difference (30%) over the face in most zones defined in an individual. The iso-thickness zone hypothesis is not valid if the 'constant' thickness criterion is set to be 10% for all zones. Software algorithm for automatically detecting the facial soft tissue thickness is developed and validated to be effective (5% fail rate). Thickness data is acquired from European white males, females and Chinese males. The data collected in this study is also useful in forensic science for facial reconstruction purpose. Laser scanning method has been used to obtain the facial surface profile to create a surface model into which the soft tissue layer thickness distribution around the face can be incorporated. The surface model is exported in IGES format and can be imported in CAD software. Electromagnetic space locating method is used to acquire the ultrasound probe position so as to find the position of the tissue thickness. Point-based registration method is used to integrate the ultrasound thickness data into the laser scanned surface model to create a soft tissue shell solid model. The model is exported in IGES data format so that it can be imported into a finite element analysis package for further processing.

Abstract:
Echocardiographic strain imaging, also known as deformation imaging, has been developed as a means to objectively quantify regional and global myocardial function. First introduced as a post-processing feature of tissue Doppler imaging velocity converted to strain and strain rate, strain imaging has more recently also been derived from speckle tracking analysis. Tissue Doppler imaging yields velocity information from which strain and strain rate are mathematically derived whereas two-dimensional speckle tracking yields strain information from which strain rate and velocity data are derived. Data obtained from these two different techniques may not be equivalent due to limitations inherent with each technique. Speckle tracking analysis can generate longitudinal, circumferential, and radial strain measurements and left ventricular twist. Although potentially useful, these measurements are also complicated and frequently displayed as difficult-to-interpret waveforms. Strain imaging is now considered a robust research tool and has great potential to play many roles in routine clinical practice. This chapter explains the fundamental concepts of deformation imaging, the technical features of strain imaging using tissue Doppler imaging and speckle tracking, and the strengths and weaknesses of these methods.

Abstract:
Students of geology who may have only a modest background in mathematics need to become familiar with the theories of stress, strain, and other tensor quantities, so that they can follow, and apply to their own research, developments in modern, quantitative geology. This book, based on a course taught by the author at UCLA, can provide the proper introduction. Included throughout the eight chapters are 136 complex problems, advancing from vector algebra in standard and subscript notations, to the mathematical description of finite strain and its compounding and decomposition. Fully worked solutions to the problems make up the largest part of the book. With their help, students can monitor their progress, and geologists will be able to utilize subscript and matrix notations and formulate and solve tensor problems on their own. The book can be successfully used by anyone with some training in calculus and the rudiments of differential equations.

Biomechanics, defined literally, is the mechanics of living systems. Human biomechanics involves the study of mechanical aspects of human movement. It is the science studying the internal and external forces experienced by the human and the effects of such forces. Nigg and Herzog (2007) highlight that forces may result in movement of body segments, deformation of biological materials, or biological changes in the tissue(s) on which they act. Thus biomechanics can involve the study of human movement and factors that affect this movement, deformation of biological structures and factors that influence this, and the biological effects of locally acting forces on living tissue (e.g. effects on growth development or injuries)....

Abstract:
Modern echocardiographic systems allow the quantitative and qualitative assessment of regional myocardial function by measuring velocity, motion, deformation, and other parameters of myocardial function.Both colour Doppler (CD) and spectral Doppler modes provide one-dimensional estimates of velocity. From CD data only, further parameters can be derived. Tracking techniques have recently been introduced which provide all parameters two-dimensionally, but at the cost of lower temporal resolution.Several clinical applications have been proposed, including regional and global systolic function assessment, evaluation of diastolic cardiac properties, and assessment of ventricular dyssynchrony.This chapter provides an introduction to the method of Doppler- and tracking-based function assessment and provides a basis for understanding its different clinical applications.

Abstract:
AbstractPredicting earthquakes is a long-desired goal. The main challenge is to identify precursory signals that reliably predict the impending earthquake. Since hydrological and hydrogeochemical properties and processes can be very sensitive to minute strains, the hope is that measurements from hydrological systems might record precursory rock deformation that would otherwise be undetectable. Of the many hundreds of studies, we review a subset to illustrate how signals can be challenging to interpret and highlight questions raised by observations—examples come from China, Japan, Taiwan, India, the USA, Russia, France, Italy and Iceland. All are retrospective studies. Some signals seem to have no other explanation than being precursory, however, rarely is enough data available to undertake a thorough analysis. Some hydrological precursors might be recording deformation events that are slower than traditional earthquakes (and hence usually harder to detect). Long times series of data are critical for both identifying putative precursors and assessing their origin and reliability.

Abstract:
How can a reader from 1993 attend to a text from the 1310s? This question haunts the text Claude Lefort devotes to Dante’s Monarchia. It is certainly a question of returning to the content of Dante’s essay, but also of nourishing contemporary reflection: reading a text also means yielding to inquiries that do not always belong to it, and testing, by this deformation and transformation, its fruitfulness for today. Can one thus oppose to the government of the One something that would be more like a community of ones? Can one hear in Dante the sketch of a thought of the common?

Abstract:
Magnetic responsive materials can be used in a variety of applications. For structural applications, the ability to create tunable moduli from relatively soft materials with applied electromagnetic stimuli can be advantageous for light-weight protection. This study investigated magnetorheological composite materials involving carbonyl iron particles (CIP) embedded into two different systems. The first material system was a model cementitious system of CIP and kaolinite clay dispersed in mineral oil. The magnetorheological behaviors were investigated by using parallel plates with an attached magnetic accessory to evaluate deformations up to 1 T. The yield stress of these slurries was measured by using rotational and oscillatory experiments and was found to be controllable based on CIP loading and magnetic field strength with yield stresses ranging from 10 to 104 Pa. The second material system utilized a polystyrene-butadiene rubber solvent-cast films with CIP embedded. The flexible matrix can stiffen and become rigid when an external field is applied. For CIP loadings of 8% and 17% vol %, the storage modulus response for each loading stiffened by 22% and 74%, respectively.

Full text
Abstract:
Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.

Full text
Abstract:
This short pedagogical movie illustrates an effect in nuclear physics called backbending which was first observed in the study of the rotational behavior of rapidly rotating rare-earth nuclei in Stockholm, Sweden in 1971. The video contains a mechanical analog utilizing rare-earth magnets and rotating gyroscopes on a turntable along with some historic spectra and papers associated with this landmark discovery together with its explanation in terms of the Coriolis induced uncoupling and rotational alignment of a specific pair of particles occupying high-j intruder orbitals. Thus backbending represents a crossing in energy of the groundstate, or vacuum, rotational band by another band which has two unpaired high-j nucleons (two quasi-particles) with their individual angular momenta aligned with the rotation axis of the rapidly rotating nucleus. Backbending was a major surprise which pushed the field of nuclear structure physics forward but which is now sufficiently well understood that it can be used as a precision spectroscopic tool providing useful insight for example, into nuclear pairing correlations and changes in the latter due to blocking effects and quasi-particle seniority, nuclear deformation, the excited configurations of particular rotational structures and the placement of proton and neutron intruder orbitals at the Fermi surface.

STRESS RESPONSE AND INITIAL STIFFNESS OF SIDE PLATE CONNECTIONS TO WCFT COLUMNS. The Hong Kong Institute of Steel Construction, September 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.9.

Full text
Abstract:
To study the mechanism of load transfer in double-side-plate connections between I-beams and wall-type concrete-filled steel tubular columns, a pseudo-static experiment and finite element analysis were conducted for two full-scaled specimens. The results revealed that the primary load was transmitted along an S-shaped path in the side plate, and the primary strain occurred in an X-shaped region between the left and right steel beam flanges. The shear force in the steel beam web was transmitted first to the side plate centre and then to the joint area, where the side plate, steel tube web, and concrete all resisted the internal force. Based on principal component methods, a calculation formula was established for initial rotational stiffness that comprehensively considers the influence of the tensions, compression, and shear deformation of the cover plate, side plate, and web. Comparing this formula with an existing model showed that the proposed formula is suitable for new types of side plate joints. Moreover, it can accurately calculate the initial rotational stiffness of the joint, thus providing a reliable basis for future engineering design.
