Abstract:
This article presents an investigation into exact and distorted similitudes and the related scaling laws for the analysis of the dynamic response of rectangular flexural plates. The response of a given model in similitude is determined from a generalization of the modal approach, which allows the use the mode shapes and natural frequencies in order to establish scaling laws. Analytical models of simply supported rectangular plates are used to produce both the original and distorted model responses. Some highlights about the distribution of the natural frequencies, the forced response and the energy response are given. The results show that, with the proposed methodology, it is possible to reproduce with good confidence the response of the reference plate, even if distorted models are used.

Abstract:
This paper evaluates the dynamic flexural response of sandstone from the Paskapoo formation in Alberta. Sandstone prisms were subjected to quasi-static flexure as per ASTM while a drop-weight impact tester was employed to generate stress rates up to 108 kPa/s. Companion testing under quasi-static compression on sandstone cylinders helped establish baseline properties including the compressive strength, elastic modulus, and Poisson’s ratio. It was found that the flexural strength and fracture toughness of Paskapoo sandstone obey stress rate sensitive models developed originally for concrete. However, the fracture toughness was more stress rate sensitive than its flexural strength.

Abstract:
This paper investigates theoretical flexural response of a partly overlapped piezoceramic PZT sensor and actuator pair which is attached on an infinite beam. In this study, three different overlapped lengths between the piezo sensor and actuator are considered and the response of each sensor and actuator is modeled theoretically and analyzed in the aspect of wave propagation in the beam. The out-of-plane flexural waves due to the action of the actuator are modeled in the beam and the sensor is modeled to detect the flexural waves. Because of the characteristics of the partly overlapped sensor and actuator pair, the sensor-actuator responses show specific properties after numerical analysis. In terms of frequency response function, the results of the three different partly overlapped cases display the magnitude and phase responses provide a better understanding in designing a vibration control system.

Abstract:

In support of crashworthiness studies of composite airframes, the present study was undertaken to understand the large deflection flexural response and failure of graphite-epoxy laminated beams. The beam specimens were subjected to eccentric axial impact loads and to static eccentric axial loads, in order to assess the damage caused by impact.

A geometrically and materially nonlinear analysis of the response and failure of the static test specimens is presented. The analysis employed an incremental, noniterative finite element model based on the Kantrovich method and a corotational solution technique. Width-wise effects are included by assuming specific forms of the displacements across the width, with length-wise variation introduced as a degree of freedom. This one-dimensional, 22 degree of freedom finite element accurately predicted the load-deflection and strain-deflection responses of the static test specimens.

Inclusion of nonlinear material behavior was found to be important in correctly predicting load-deflection response of uniaxial materials, while inclusion of width-wise effects was determined to be more important for laminates with off-axis plies due to the existence of coupling between bending and twisting curvatures (D16and D26). Once material nonlinearity begins to occur in flexure, even symmetric laminates exhibit bending-stretching coupling due to different material response in tension and compression.

Abstract:
The structural response of unreinforced masonry elements strengthened with hybrid elastomeric/fiber materials was investigated through material characterization and flexural experiments. Material characterization tests were performed on various unreinforced and reinforced elastomeric materials to identify those materials that were best suited for use as structural retrofits. After material characterization was completed, the three most promising material systems were selected for further investigation, including one unreinforced elastomer film and two reinforced elastomer films with fiber orientations at 0/90° and +/- 45° relative to the major axis of the masonry elements. A series of four-point bending tests were performed on the selected masonry and epoxy bonded elastomer/fiber hybrid retrofits to determine the structural response of the composite systems. The experimental load-deformation response was used, along with material characterization results, in the development of a semi-empirical model to predict the static moment capacity of the strengthened masonry system. This model will be used in the development of reliable design criteria for masonry walls strengthened with these advanced materials.

Abstract:
A model is presented to use normalized multi-linear tension and compression material characteristics of strain-hardening textile reinforced concrete and derive closed form expressions for predicting moment-curvature capacity. A set of design equations are derived and simplified for use in spreadsheet based applications. The model is applicable for both strain-softening and strainhardening materials. The predictability of the simplified model is checked by model calibration and development of design charts for moment capacity and stress developed throughout the cross section of a flexural member. Model is calibrated by predicting the results of Alkali Resistant Glass and Polyethylene fabrics. A case for the flexural design of Glass Fiber Reinforced Concrete (GFRC) specimen as a simply supported beam subjected to distributed load is used to demonstrate the design procedure.

Ultramicrotomy is the process of cutting specimens into submicron-thickness slices for subsequent imaging using a scanning electron microscope (SEM). Ultramicrotomes, devices that employ this process, have incorporated oscillations into this process to reduce the damage done on each slice. Extensive research has been made in trying to identify the appropriate settings: frequency, amplitude of cut, and feed speed, to maximize the reduction of this damage. Currently, however, there exists no research that tries to understand why the introduction of oscillations provides such a reduction in damage. To understand the mechanics behind oscillatory orthogonal cutting, specifically in ultramicrotomy, the frequency response of a compliant mechanism must be understood. The frequency response of a complaint flexural stage driven by piezoelectric actuator was measured. Using a Linear Variable Differential Transformer (LVDT) and a dynamic signal analyzer via LabView, the frequency response of the stage was measured from 100Hz to 10000Hz. A model was then fitted to the measured response. Using this model, a comparison between a simulated-reference response of the position of the stage to the output response of the model showed that a controller was required to minimize the error in the position of the stage.

Abstract:
This paper presents results of an experimental investigation to study the structural performance and deformability of a concrete bridge deck reinforced with corrosion resistant reinforcing (CRR) bars, i.e., bars that exhibit improved corrosion resistance when embedded in concrete as compared to traditional black steel. Flexural tests of one-way slabs were conducted to simulate negative transverse flexure over a bridge girder as assumed in the commonly employed strip design method. The bar types studied were Grade 60 (uncoated), epoxy-coated reinforcing (ECR, Grade 60), Enduramet 32 stainless steel, 2304 stainless steel, MMFX2, and glass fiber reinforced polymer (GFRP). The experimental program was designed to evaluate how a one-to-one replacement of the Grade 60 with CRR, a reduction of concrete top clear cover, and a reduction in bar quantities in the bridge deck top mat influences flexural performance at service and ultimate limit states. Moment-curvature predictions from the computer-based sectional analysis program Response 2000 were consistent with the tested results, demonstrating its viability for use with high strength and non-metallic bar without a defined yield plateau.    
    Deformability of the concrete slab-strip specimens was defined with ultimate-to-service level ratios of midspan deflection and curvature. The MMFX2 and Enduramet 32 one-to-one replacement specimens had deformability consistent with the Grade 60 controls, demonstrating that bridge deck slabs employing high strength reinforcement without a defined yield plateau can still provide sufficient ductility at an ultimate limit state. A reduction in bar quantity and cover provided acceptable levels of ductility for the 2304 specimens and MMFX2 reinforced slabs.

Abstract:
Throughout the ocean basins many broad regions of anomalously shallow topography exist that do not fit the widely accepted model of conductive plate cooling and subsidence as a function of lithospheric age. These ‘swells’ often coincide with positive geoid, Free-air gravity and heat flow anomalies as well as groups of ocean islands and seamounts. Various mechanisms have been proposed to explain how this anomalous topography is isostatically supported at depth, including increased crustal buoyancy and dynamic asthenospheric support. The Cape Verde Swell is the largest oceanic mid-plate swell on Earth at ~1800 km in diameter, with a crest ~2.2 km high, and positive geoid, gravity and heat flow anomalies of 8 m, 30 mGal and 10-15 mW m-2, respectively. These characteristics and its location on the slow-to-stationary African Plate, which concentrates the volcanism and associated geophysical anomalies within a relatively small areal extent, makes the Cape Verde Swell an ideal location to test the various proposed mechanisms for swell support. Wide-angle seismic refraction data along an ~474 km profile, extending from the Cape Verde Swell crest, is analysed and modelled to produce a 2-D velocity-depth model of the crustal structure. The resulting model reveals no widespread thickening of the lower oceanic basement, despite evidence for localised thickening beneath the islands from other studies. Subsequent 3-D ‘whole plate’ lithospheric flexure modelling reveals that, on a regional scale, the plate is stronger than expected based on its age, with some evidence for localised weakening around the islands. Overall, the results of this study suggest that the anomalously shallow topography of the Cape Verde Swell is primarily maintained by a dynamic upwelling of hot, low density material impinging on the base of the lithosphere. Over time, conduction from this hot column has thermally rejuvenated the lithosphere on a local scale, leading to additional uplift, melting and volcanism associated with the islands.

Abstract:
Abstract The restoring forces on membranes are due to the applied tension, while the restoring forces for plates are due to the flexural rigidity of the plate’s material. The transition to two dimensions introduces some features that did not show up in our analysis of one-dimensional vibrating systems. Instead of applying boundary conditions at one or two points, those constraints will have to be applied along a line or a curve. In this way, incorporation of the boundary condition is linked inexorably to the choice of coordinate systems used to describe the resultant normal mode shape functions. For two-dimensional vibrators, two indices are required to specify the frequency of a normal mode, fm,n, with the number of modes in a given frequency interval increasing in proportion to the center frequency of the interval, even though that interval remains a fixed frequency span. It is also possible that modes with different mode numbers might correspond to the same frequency of vibration, a situation that is designated as “modal degeneracy.” A membrane’s response to sound pressures provides the basis for broadband condenser microphone technology that produces signals related to the electrical properties of that capacitor and the charge stored on its plates.

Abstract:
Steel/polymer/steel laminate sheets, commonly known as laminated steel, received renewed interest recently for their superior noise damping properties in automotive applications. Earlier work in the literature indicates that the tensile properties of the laminated steel follow the prediction of the rule of mixtures. The flexural response of the laminated steel, however, depends on the type of the sandwich configuration. The flexural rigidity of the vibration-damping type of laminated steel is lower than the value calculated using beam theory. The finite element (FE) modeling techniques that might be suitable for a particular type of laminated steel are directly linked to how the flexural rigidity of the laminated steel conforms to the prediction using the beam theory. This paper examines the flexural response of the vibration-damping type of laminated steel through comparison of beam theory predictions with the experimental results for cantilever beam and three-point bending configurations. In addition, tensile and shear tests were conducted. The paper evaluates some FE modeling techniques in LS-DYNA for the analysis of laminated steel under flexural loading. The recommended modeling method was also examined for tensile loading.

Abstract:
Polymer composite structures are usually subjected to large flexural loadings, so the flexural behavior of these structures and their constituents are critical to their use. A novel approach for polymeric materials with strain softening model in tension and compression is developed to investigate the flexural behavior of Epon E 863. The tension and compression model consists of a bilinear ascending curve in pre-peak, strain softening followed by constant plastic flow in the post-peak response. The effects of softening localization on flexural response are considered. Local stress strain tension and compression responses, using digital image correlation system, are used for material characterization. Closed form expressions for flexural behavior are developed. The structural response of beams under three and four point bending and round plate on three symmetrical supports are studied experimentally and analytically. Results show that direct use of uniaxial tension and compression stress strain models underestimates the flexural load carrying capacity. Flexural over-strength factor obtained from inverse analysis of beam under three point bending is conservative and it could be used to modify the constitutive models for analyzing a structural system.

Abstract:
Abstract The wave-mode representation is utilized to obtain a more efficient form to the conventional transfer matrix method for bending vibrations of beams. The proposed improvement is based on a phase-variable canonical state representation of the equation governing the time-harmonic flexural vibrations of a beam. Transfer matrices are obtained for external forces, step-change of beam properties, intermediate supports and for boundaries. The transfer matrices are utilized to obtain the vibration response of a point-excited single-span beam with general boundary conditions. The general characteristic equation and the transfer mobility of a single-span beam are determined. The application of the analytical results are demonstrated on physical structures with different boundary conditions. A hybrid model is developed to incorporate measured impedance of nonideal boundaries into the transfer matrix method. The analytical results are found to be in excellent agreement with experimental measurements.
