Computational Structural Mechanics

Abaqus®

Overview

The U.S. Department of Transportation´s (USDOT´s) current and near-future need for computational structural mechanics led the Transportation Research and Analysis Computing Center (TRACC) researchers to select the commercial Abaqus software as one of TRACC´s primary structural analysis tool. It will initially be used for modeling and simulating asphalt pavement response to traffic loading, multiscale modeling of road materials and highway performance assessment. USDOT University Transportation Centers currently use Abaqus, and will not require any additional training to use the software at TRACC. TRACC has a 32 CPU (core) license with Dassault Systèmes Simulia Corporation for use of the Abaqus suite of codes–primarily for university researchers. The TRACC Abaqus license includes the following major analysis products:

  • Abaqus/Standard
  • Abaqus/Explicit
  • Abaqus/Aqua
  • Abaqus/Design
  • one seat of Abaqus/CAE, which provides a complete interactive environment for creating models, submitting and monitoring analysis jobs, and viewing and manipulating simulation results.

Current TRACC Applications

Researchers at Michigan Technological University are using Abaqus to develop a microstructure-based modeling approach to characterize asphalt materials. At the Louisiana Transportation Research Center, researchers are developing finite element models to simulate performance of pavement structures, specifically for rutting performance of the chemically stabilized base/subbase materials under accelerated loading.
