Abstract:
AbstractIn a series of three articles, fundamentals of a vector form intrinsic finite element procedure (VFIFE) are summarized. The procedure is designed to calculate motions of a system of rigid and deformable bodies. The motion may include large rigid body motions and large geometrical changes. Newton's law, or a work principle, for particle is assumed to derive the governing equations of motion. They are obtained by using a set of deformation coordinates for the description of kinematics. A convected material frame approach is proposed to handle very large deformations. Numerical results are calculated by using an explicit algorithm. In the first article, using the plane frame element as an example, basic procedures are described. In the accompanied articles, plane solid elements, convected material frame procedures and numerical results of patch tests are given.

Abstract:
In this paper a finite element procedure for modelling the viscoelastic behaviour of orthotropic composites is presented. The procedure uses the commercially available finite element package ABAQUS and requires no code development. The procedure utilises two coincident shell elements to model the orthotropic viscoelastic behaviour of a composite laminate. The first element exhibits isotropic and viscoelastic behaviour, while the second element exhibits orthotropic and elastic behaviour. The elements are superimposed in such a way that they are coincident. That is, the two shell elements share the same nodes and hence deform together. Consequently, it is expected that this combined hybrid model will exhibit combined orthotropic and viscoelastic behaviour. Numerical examples are presented to illustrate the capability and accuracy of the new procedure.

Abstract:
Finite-element modeling and use of appropriate analytical techniques play a significant role in producing a reliable and economic design for ship hull structures subjected to dynamic loading. The paper presents investigations carried out for the dynamic response analysis of ship hull structures using the finite-element method. A simple and efficient interactive graphical preprocessing technique based on the "keynode" concept and assembly-line procedure is used to develop the finite-element model of the hull structure. The technique makes use of the body plan of a ship hull to build the finite-element model through an interactive session. Stiffened plate/shell finite elements suitable to model the hull structure are formulated and used to model the structure. The finite elements take into account arbitrary placement of stiffeners in an element without increasing the number of degrees-of-freedom of the element. A three-dimensional finite-element model and a procedure based on the Bubnov-Galerkin residual approach are employed to evaluate the effects of interaction between the ship hull and water. Mode superposition technique is used to conduct the dynamic response analysis. The efficiency of the finite elements and the procedures is demonstrated through dynamic analysis of a submerged cantilever plate and a barge when both are subjected to sinusoidal forces. The dynamic responses exhibit expected behavior of the structure and a comparison with the results available in the literature indicate superior performance of the finite element and methodologies developed. Thus, the finite-element models and the procedures are found to be efficient and hence suitable for the dynamic analysis of similar structures.

Abstract:
The aim of the article is to justify a new element in the procedure for the extradition of a person for criminal prosecution or sentence execution. This element is the checking for compliance with internationally recognized standards of the conditions of the possible detention before trial, incarceration, as well as during transfer, in the country this person is extradited to. The source basis of the study were materials of the European Court of Human Rights, courts of the United Kingdom of Great Britain and Northern Ireland, the Supreme Court of the Russian Federation, the Federal Penitentiary Service of Russia, the Main Directorate of International Legal Cooperation of the Prosecutor General’s Office of the Russian Federation, materials of checks of confinement conditions in Russian penitentiary institutions. Materials of checks of confinement conditions in specific penitentiary institutions have been supplemented with materials of checks of conditions for transferring prisoners in the Russian Federation. The study is based on the application of the method of participatory observation expressed in the collection of factual material during direct participation in the work of the Main Directorate of International Legal Cooperation of the General Prosecutor’s Office of the Russian Federation in organizing checks by foreign experts of the confinement conditions of prisoners when deciding on extradition. Methods of observation, interviewing, experiment, analysis, comparison, and others were also used. The analysis of the available materials and the author’s own practice showed that foreign partners began to actively use information about unsatisfactory confinement conditions in prisons in specific cases as a basis for refusal to extradite people to Russia. When deciding on the extradition of persons detained at the request of the Russian side for criminal prosecution, the practice of foreign partners has introduced the organization of regular checks of the alleged confinement conditions in the Russian Federation on specific criminal cases in relation to specific persons. In order to overcome the emerging problems, on a contractual basis, foreign authoritative specialists are organizing inspections of the conditions in various penitentiary institutions. The results of such inspections in specific penitentiary institutions are of direct importance in matters of extradition in specific cases. On the basis of this material, the need was justified to include an additional element in the theoretical and legislative model of extradition, which no one has yet mentioned in the legal literature – checking the conditions of the possible detention of the extradited person before trial and incarceration. In order to overcome the negative trends, a set of measures at three different levels has been proposed to bring the conditions of the person extradited during the transfer to Russia in line with internationally recognized standards.

Abstract:
This paper presents an advanced numerical methodology which aims to improve virtually any metal forming processes. It is based on elastoplastic constitutive equations accounting for non-linear mixed isotropic and kinematic hardening “strongly” coupled with isotropic ductile damage. During simulation of metal forming processes, where large plastic deformations with ductile damage occur, severe mesh distorsion takes place after a finite number of incremental steps. Hence an automatic mesh generation with remeshing capabilities is essential to carry out the finite element analysis. Besides, when damage is taken into account a kill element procedure is needed to eliminate the fully damaged elements in order to simulate the growth of macroscopic cracks. The necessary steps to remesh a damaged structure in finite element simulation of forming processes including damage occurrence (initiation and growth) are given. An important part of this procedure is constituted by geometrical and physical error estimates. The meshing and remeshing procedures are automatic and are implemented in a computational finite element analysis package (ABAQUS/Explicit solver using the Vumat user subroutine). Some numerical results are presented to show the capability of the proposed procedure to predict the damage initiation and growth during the metal forming processes.

Abstract:
A procedure is developed to integrate analytical solutions to problems featuring random media with Monte Carlo simulations in order to improve the efficiency of the simulations. This is achieved by developing a common theoretical framework that encompasses Monte Carlo procedures as well as various expansion solution techniques. This framework can be perceived as a natural extension of hybrid deterministic finite element procedures whereby refinement is achieved by simultaneously increasing the number of elements as well as the degree of interpolation within each element.

Abstract:
As a result of Human Factors evaluations of procedures associated with incidents at Rocky Flats Plant (RFP) it was determined that the existing procedure format created significant opportunities for confusion in their attempt to convey information about a work process. For instance, there was no mechanism to clearly identify the participants and their roles during the Instructions portion of the procedure. In addition, procedure authors frequently used complex logic to convey a series of contingent actions within steps. It was also difficult to discern the actual procedure steps from other types of information in the procedure. These and other inadequacies prompted the Human Factors Engineering (HFE) department to propose solutions to these problems that followed well-researched principles of cognitive psychology, dealing with how humans process information. Format and style contribute to procedure usability, and therefore to safety and efficiency in operations governed by the procedures. Since it was difficult to tie specific performance failures to specific format and style characteristics and thereby clearly define costs and benefits, it was difficult on that basis to sell the idea that changes in procedure format and style were really necessary to improve safety and efficiency. In addition, we found that the socio-political systems governing this process, particularly at the subprocess interface level, were not functioning efficiently. Both the technological aspects of the process and the socio-political aspects were contributing to waste and considerable re-work. Fixing the customer feedback loop to the process owners not only minimized re-work and waste, but also provided the data to persuade subprocess owners to make the necessary changes that heretofore were being met with great resistance.

Abstract:
This thesis presents an adaptive finite element procedure for electromagnetic scattering problems in two dimensions. The work addresses the issues of higher order basis functions and demonstrates their advantages over lower order approximations. A new a-posteriori error estimator is derived which is capable of producing bounds on non-linear outputs of the scattering problem. Subsequently, this is used to automatically adapt both the polynomial order and the mesh spacing. The effectiveness of the procedures are demonstrated through a series of examples.

Abstract:
Finite element optimum meshes are synthesized by the use of thermal expansion principles in conjunction with an analogous temperature field computed from the element strain energy contents. Elements having high strain energy contents are shrunk and those with low strain energy contents are expanded until all elements contain the same amount of strain energy. Deviatoric strain energy is also used in place of the strain energy as the objective function for the optimization method. Both objective functions yield significant improvements of the meshes after only a few iterations. In one test case, the errors in the maximum stresses are reduced by more than 1/3 after 1 iteration. In another test case, the error in the stress concentration factor is reduced by more than 3/4 after 7 iterations.

Abstract:
Complex engineering problems need appropriate constitutive laws such as Disturbed State Concept (DSC), as well as robust accurate computational analysis methods such as adaptive and stochastic finite element methods (FEM). DSC provides a unified basis for constitutive modeling including elastic, plastic and creep deformations, microcracking, damage and softening, stiffening, and cyclic fatigue under thermomechanical loading. It includes intrinsical regularization, localization, characteristic dimension and avoidance of spurious mesh dependence. It also leads to new procedures for adaptive FEM and stochastic FEM. Adaptive FEM is a method to adapt or guide itself to better subsequent computation by use of previous computational information so as to achieve prescribed accuracy. It's a powerful procedure for analyzing deformation of special problems such as interfaces and joints and shear bands, and complex materials with both hardening and softening. An adaptive finite element procedure with combined Disturbance-Hybrid stress error estimator/remeshing indicator is proposed and tested by comparing with some published results, and the corresponding user-interactive unified DSC finite element program with more than 10 options is developed and applied to thermal analysis of electronic packaging problems. Unlike deterministic analysis methods, stochastic FEM approach further considers the random variations of involved parameters to further make the deterministic constitutive and numerical modeling more realistic in a statistical manner. Traditional stochastic FEM is reviewed and a new efficient DSC stochastic FEM is formulated for reliability analysis of electronic packaging problems. The computer visualization and animation are applied to display the computed results for the purpose of easier use and interpretation of the results, which will be one of major trends for engineering application of computational methods. In this dissertation, combined study is carried out from a comprehensive (computational and constitutive) viewpoint, and the practical and academic values of the adaptive and stochastic DSC finite element procedures for electronic packaging problems will be demonstrated.

Abstract:
Abstract A methodology initially proposed for authomatic mesh generation of triangular and quadrilateral finite element discretizations in linear two-dimension problems is now extended to material nonlinear analysis. The technique, which is based on a h-adaptive process, is capable of achieving a specified discretization density using a powerful mesh generator. The element solutions at the nodes are obtained through a general stress recovery procedure employing an a posteriori error estimator. The constitutive equation is approached in the formulation using a flow theory to describe the elasto-plastic material behavior. In this study the von Mises condition is employed for the state of multiaxial stress corresponding to the start of plastic flow, the normality condition furnishes a flow rule in the plastic strain increments subsequent to yielding and the kinematic hardening is assumed as hardening rule. The adaptive procedure is based on the complete mesh regeneration and specific mesh requirements (boundary conditions, geometry definitions and space node function), and aims for an optimality condition with the least number of elements that yields an uniform error distribution in all elements. In the stress recovery process the nodal values are assumed to belong to a polinomial expansion defined over patches of elements adjoining a particular assembly node considered. The nodal point parameters, at each element, are obtained using a least square fit of superconvergent sampling points existing in the patch. The material uniaxial elasto-plastic constitutive behavior is represented using overlays, defined over small strain increments, allowing for the representation of the material kinematic hardening behavior beyond the classical bilinear relation. The procedure error estimation is obtained from differences between the post-processed stress gradients and those from the finite element solutions. The energy error norm associated with stress field diferences and the finite element strain energy gives an effective error estimate, used for comparison with the process tolerance. Evaluation of the proposed technique is presented through two numerical sampling analyses that illustrate its applicability in the improvement of the solution accurance of general two-dimension finite element model solutions.

Various parameters were considered for analysis like pin diameter, distance from fracture site, number of pins, distance of the rail from the fracture site, effect of width and length of the rail on gap closing, angle of fracture and pin angle. FEMLAB 2.3 is used for both modeling and analysis. A 2D model is constructed with the bone joint consisting of first metatarsal and cuneiform along with the fixation device. The dimensions of the model are taken similar to a prototype model of the foot and mini fixation device. Simple Static analysis is done as a beginning case which will be later developed to dynamic case.

Abstract:
Abstract The adaptive remeshing and rezoning procedures developed for large deformation finite element analysis using viscoplastic material model are presented in two dimensions. The adaptive procedure is driven by the posteriori error estimation technique. The nonlinear error estimators based on the energy rate norm error and the L2 norm error of incremental total strains are used for error computation. The remeshing algorithm creates new acceptable meshes in the course of the deformation process without any loss of geometric information. The remeshing of the current geometry is achieved using the boundary refinement technique. This technique is observed to be sufficiently accurate in problems where mesh refinement is largely required at the boundary or very close to the boundary of the structure. The rezoning procedure is then used to accurately interpolate the solution variables from the existing mesh to the new adaptively created mesh. The element subdivision approach is used during the rezoning process. The adaptive remeshing and rezoning procedures are developed for 6-node triangular element. These procedures are implemented in the general purpose finite element program, ANSYS [13], and are validated by solving two complex large strain examples. In both examples, these procedures are successful in achieving very high deformation levels in a structure.

Abstract:
Achieving uniform bolt preloads is an important and difficult issue, when bolting up a pipe flange connection with a number of bolts. Repeated bolt-up operations are, therefore, commonly conducted to get uniform bolt loads. In this study, an effective one-pass bolting up procedure to get uniform bolt loads is proposed by using finite element analysis with elastic interaction coefficient method being incorporated. Furthermore, multi-pass bolting up procedure is also examined to avoid high initial bolt clamping forces that might be generated in the one-pass tightening. These procedures are applied to class 300 lb 20 inch flanges with solid-metal flat gasket and compressed asbestos sheet gasket. The validity of the procedures is substantiated by conducting bolting up experiment using calculated initial clamping forces.

Abstract:
Bio-structures owe their remarkable mechanical properties to their hierarchical geometrical arrangement as well as heterogeneous material properties. This dissertation presents an integrated, interdisciplinary approach that employs computational mechanics combined with flow network analysis to gain fundamental insights into the failure mechanisms of high performance, light-weight, structured composites by examining the stress flow patterns formed in the nascent stages of loading for the rostrum of the paddlefish. The data required for the flow network analysis was generated from the finite element analysis of the rostrum. The flow network was weighted based on the parameter of interest, which is stress in the current study. The changing kinematics of the structural system was provided as input to the algorithm that computes the minimum-cut of the flow network. The proposed approach was verified using two classical problems three- and four-point bending of a simply-supported concrete beam. The current study also addresses the methodology used to prepare data in an appropriate format for a seamless transition from finite element binary database files to the abstract mathematical domain needed for the network flow analysis. A robust, platform-independent procedure was developed that efficiently handles the large datasets produced by the finite element simulations. Results from computational mechanics using Abaqus and complex network analysis are presented.

Abstract:
This project summarizes the results from 2000–2020and evaluates the trueness andthequality control (QC) procedures of the ongoing polycyclic aromatic hydrocarbon (PAH)and trace element measurements in Finlandrelating to Air Quality (AQ) Directive 2004/107/EC. The evaluation was focused on benzo(a)pyrene and other PAH compounds as well as arsenic, cadmium and nickel in PM10and deposition. Additionally, it included lead and other metals in PM10and deposition, gaseous mercury and mercury deposition, andbriefly other specificAQ measurements such as volatile organic compounds (VOC)and PM2.5chemical composition. This project was conducted by the National Reference Laboratory on air quality and thiswas the first time these measurements were assessed. A major part of the project was field and laboratory audits of the ongoing PAH and metal measurements. Other measurements were briefly evaluated through interviews and available literature. In addition, the national AQ database, the expertise of local measurement networks and related publications were utilised. In total, all theseven measurement networks performing PAH and metal measurements in 2019–2020took part in the audits. Eleven stations were audited while these measurements are performed at 22 AQ stations in Finland. For the large networks, one station was chosen to represent the performance of the network. The audits included also six laboratories performing the analysis of the collected samples. The audits revealed the compliance of the measurements with the AQ Decree 113/2017, Directive 2004/107/EC and Standards of the European Committee for Standardization(CEN). In addition, general information of the measurements, instruments and quality control procedures were gained. The results of the laboratory audits were confidential,but this report includes general findings, and the measurement networks were informed on the audit results with the permission of the participating laboratories. As a conclusion, the measurementmethodsusedwere mainly reference methods. Currently, all sampling methods were reference methods; however, before 2018 three networks used other methods that may have underestimated concentrations. Regarding these measurements, it should be noted the results are notcomparable with the reference method. Laboratory methods were reference methods excluding two cases, where the first was considered an acceptable equivalent method. For the other, a change to a reference method was strongly recommended and this realized in 2020. For some new measurements, the ongoing QC procedures were not yet fully established, and advice were given. Some networks used consultant for calibration and maintenance, and thus theywere not fully aware of the QC procedures. EN Standards were mostly followed. Main concerns were related to the checks of flow and calculation of measurement uncertainty, and suggestions for improvement were given. When the measurement networks implement the recommendations given inthe audits, it can be concluded that the EN Standards are adequately followed in the networks. In the ongoing sampling, clear factors risking the trueness of the result were not found. This applies also for the laboratory analyses in 2020. One network had concentrations above the target value, and theindicative measurementsshould be updated to fixed measurements.

Abstract:
As the global community works toward the Sustainable Development Goals, closer integration between governance and sectoral interventions offers a promising, yet unproven avenue for improving health service delivery. We interrogate what value an integrated governance approach, intentionally combining governance and sectoral investments in strategic collaboration, adds to health service readiness and delivery using data from a study in Senegal. Our quasi-experimental research design compared treatment and control communes to determine the value added of an integrated governance approach in Senegal compared to health interventions alone. Our analysis shows that integrated governance is associated with improvements in some health service delivery dimensions, specifically, in aspects of health facility access and quality. These findings—that health facilities are more open, with higher quality infrastructure and staff more frequently following correct procedures after integrated governance treatment—suggests a higher level of service readiness. We suggest that capacity building of governance structures and an emphasis on social accountability could explain the added value of integrating governance and health programming. These elements may help overcome a critical bottleneck between citizens and local government often seen with narrower sector or governance-only approaches. We discuss implications for health services in Senegal, international development program design, and further research.
