In this paper, finite element (FE) models are developed for
some of the ballasted track components including wood and concrete crossties, ballast and subgrade. A user material subroutine is employed to predict the failure of wood ties based on an
orthotropic stress criterion.
The mechanical manipulation of the equipment, however, can induce significant sudden movement of the completion tubing string near the tool’s locking mechanism. The rapid movement of the tubing string causes large relative motion and “piston effect” forces between tool components and fluid present in the wellbore.
This presentation will demonstrate how Abaqus can be used to drive design decisions at an early stage in the engine development process.
In this study, the program BSAP was developed to carry out the stiffness analysis by designer easily and quickly. BSAP has three templates; CATIA template, AFC template, and Report template.
A simplified suspension assembly for upper control arm was analyzed, tested and correlated for load deflection data. This documentation reveals the effective utilization of Bushing
connector and accurate representation of coupled Bushing and Bolt joint
in a suspension assembly
This study is shown using data from these carefully constructed laboratory experiments, we can quantify impact location, magnitude, and linear and angular accelerations of the head. The resultant forces and accelerations are applied to a fully meshed head-form created from MRI data by Simpleware.
This study is focused on analysis of post-repair behavior of composite structures. The objectives are to a) develop efficient computational approach for repaired areas, capturing processes of both damage initiation and growth; and b) demonstrate it in Abaqus on representative examples of composite repair designs.
In this paper, preliminary results from a numerical study undertaken to study abrasive wear of tillage tools by soil particles are presented. The wear process is modeled as a single sand particle scratching at a prescribed speed on the surface of a tillage tool.
The study presented that simulations agree favorably with the test results and produce higher fidelity solutions than traditional analytical or empirical blast models. The work is shown that Abaqus/Explicit can be used to accurately predict the response of a structure subjected to a near-field blast event with specific application to underbelly blast events on vehicles.
The presented work depicts results of a two-scale approach to the problem of damage and failure prediction on laminated composite structures.This work shows results of the application of the most commonly used micromechanical failure criteria applied for unidirectional composites.
