In the present study two-dimensional finite element analysis has been carried out on cantilever sheet pile wall using ABAQUS/Standard software to effect of different friction angles and its related parameters such as dilation angle, interfacial coefficient between soil-wall earth pressure distribution, deformation. From results obtained, it is found that there a significant decrease in deformat...

A simplified ITER's Diagnostic First Wall is modelled in Abaqus Finite Element software to evaluate hydrogen retention after cyclic plasma exposure, and especially, the impact of mechanical fields. Using several User Subroutines, a strongly coupled chemo-thermo-mechanical problem set solved. Hydrogen field results with or without fields are compared, during different loading phases, leading con...

The paper briefly summarizes the theoretical derivation of the objective stress rates that are work-conjugate to various finite strain tensors, and then briefly reviews several practical examples demonstrating large errors that can be used by energy inconsistent stress rates. It is concluded that the software makers should switch to the Truesdell objective stress rate, which is work-conjugate t...

The overall goal of my work is to gain insight into how tooth shape relates to its function. As a step towards this, I undertook an independent study project to learn finite element analysis (FEA) this semester, and to lay a foundation for my future Master’s thesis project work. After solving a series of problems on paper, reading through my supervisor’s work, and referring to a range of papers...

Biomechanics testing of the lumbar spine, using cadaveric specimens, has the advantage of using actual tissue, but has several disadvantages including variability between specimens and difficultly acquiring measures such as disc pressure, bone strain, and facet joint contact pressure. A simulation model addresses all of these disadvantages. The objective of this work is to develop a method to s...

An alternative numerical model for fiber reinforced concrete (FRC) compressive and bending tensile strength determination is presented in this paper. Fibers are modeled explicitly by using the Extended Finite Element Method (XFEM). method modeling fiber-matrix interaction, without need additional subroutine definition, proposed. The was evaluated experimental tests results good agreement. devel...

Variable cross-section roll forming is a new process developed on the basis of traditional constant forming. It can produce variable products flexibly and efficiently, which great significance to automobile lightweight. In this paper, rolling section longitudinal beam simulated, finite element model sheet metal established in ABAQUS software, deformation stress distribution are analyzed. conclu...

Abstract Load and shape optimisation are applied to the process of air bending optimise damage state in formed component. The enhanced elastomer is optimised, which yields a reduced due superimposed radial stresses critical area forming process. presented here twofold. First, replaced by nodal loads generate optimised for state. Second, itself via adjusting layer two kinds varying stiffness. ac...

The biomechanical properties of soft tissue derived from experimental measurements are critical for developing a reality-based model for minimally invasive surgical training and simulation. In our research, we focus on developing a biomechanical model of the liver under large tissue deformation. This paper presents the experimental apparatus, experimental data, and formulations to model the exp...

To protect passengers, large aircraft are equipped with multiple mechanisms to absorb impact energy during a crash. However, light aircraft rely only on the cabin structure to withstand the compression and energy generated during a crash. This study performed a topology optimization analysis on the model structure by using Abaqus/optimization and used strain energy as the objective function and...
