The paper mainly focuses on the chances and frontiers our research group encountered dealing with high preformance large deformations simulations in geomechanics under highly complex conditions.

This study presents a mesh objective crack band model is implemented in the generalized method of cells (GMC) micromechanics model to predict failure of a composite repeating unit cell (RUC). The micromechanics calculations are achieved using the MAC/GMC core engine within the ImMAC suite of micromechanics codes, developed at the NASA Glenn Research Center.

These gates are designed to withstand the hydrostatic and
transient pressure loads. A phenomenon that is, however, usually overlooked in the design is the hydrodynamic pressure that is built up in the system during an earthquake.

The study was performed using scaled Tabas earthquake acceleration as the input seismic motion. The results of the simulations are presented in form of a parametric study on the effect of culvert tunnel length, venting geometry, dimension and topology of the vents,
existence of notch at the vent opening, and also the cavitation effect.

The methodology is applied to the analysis of dams, lock gates, and large storage tanks, incorporating in some cases a comparison with the results produced by means of simplified analytical procedures.

This paper shows that the lateral stiffness analysis result of vehicle suspension can be improved with the accurate bearing stiffness model correlated with experimental vehicle test data and also, shows which design parameters contribute to lateral stiffness of vehicle suspension.

This report indicates that the 3D electro-thermal model employed in this study characterizes the electro-thermal behavior of the Li-ion battery cells reasonably well.

The objective of this study is to provide an analysis portal to increase their usage through a larger community. SLM has been used to host the automation of the processes and manage the lifecycle of the data used and generated. This report will describe the initial objectives, the implementation experience and the results obtained.

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.

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.

HI,

        Am trying to model prestressed box girder bridge for high speed railway analysis.Am not getting how to model prestressing force using ABAQUS/CAE.I have seen that it's not possible with CAE. Please say me an alternative way to model prestressing force.

        I tried by "embedding" parabolic wire element (tendon) in the concrete and applied prestressing force as axial force and udl(giving line load on tendon,upward).But my results not matching with the theoritical value.Is this a correct way of approximating prestressing force?? 

Hi guys,

I am tring to model a thin strip of a material(E= 2*e6 MPA and poisson's ratio=0.5) into mobius strip. I should do this by applying Boundary conditions(rotation) or loads. When I tried this simulation, it kept getting aborted when I gave rotation(with respect to the axis parallel to the length) more than 3 radians. I tried refining the mesh but it di not help. Can any one suggest me how to go forward with this simulation or suggest me any other way of achieving this.

 note: i used quad shell elements
