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.
This study will be shown how to perform this integration with Isight as a manager of several different solvers and how all work together. The key aspect of the optimization process is the ability to integrate different analysis models such as: injection, structural, thermal, modal and etc.
This study shows a plug-in for Abaqus/CAE that helps the user to define a tunneling, excavation and temporary structures, with support facility and other geotechnical analysis. The paper explores the steps to define a geotechnical analysis and Abaqus/CAE capabilities. It also includes two examples of the plugin usage: a tunnel and a retaining wall.
In this study, using a UDMGINI subroutine, stress components relative to a predefined osteon orientation were computed and an anisotropic damage criterion was used to determine damage initiation and to predict crack propagation.
In this study, FEA using Abaqus is combined with statistical and probabilistic analysis using Isight to demonstrate how these techniques work together to evaluate the robustness of medical device designs.
This paper presents helical buckling analyses are performed primarily to determine the critical effective axial load at which the inner pipe of a pipe-in-pipe (PiP) system snaps into a sinusoidal or helical buckling deformation mode.
The work presented demonstrates how Isight may be used to drive STAR-CCM+ and CATIA V5 for parametric optimization. A key requirement from the OEM was to remove time-consuming manual iterations from the design process and this example case was setup to demonstrate the automatic optimization process using their existing design and analysis tools.
This study allows mechanical engineering models to be used in place of legacy constructive solid geometry descriptions, which are far less sophisticated. This capability also allows for the seamless integration of radiation transport calculations with analysis of the resulting thermal and mechanical effects on materials.
The objective of the present study was to develop and validate an explicit FE model of the lumbosacral spine and the FSU L4-L5 using patient-specific in vitro data and to evaluate load-deflection characteristics, contact mechanics and efficiency of the FSU. It is also to create a probabilistic model to efficiently predict the performance of the FSU by incorporating disc and ligament material variability.
