Discussion Overview

The discussion revolves around the use of the Gibson-Ashby model for simulating the mechanical properties of polyurethane foam in Abaqus, specifically focusing on whether there is a library available for this model and addressing issues related to implementing user subroutines in Abaqus.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks assistance in finding a library for the Gibson-Ashby model in Abaqus for their bachelor thesis.
  • Another participant suggests consulting the Abaqus Theory Guide, specifically the chapter on "Models for crushable foams," to determine if those models meet the original participant's needs.
  • A different participant expresses their intention to simulate a tensile test using the Gibson-Ashby model, assuming linear elastic behavior, but encounters a compilation error with the UMAT subroutine.
  • One reply advises checking the setup for Abaqus subroutines and suggests verifying if any analyses can be run with the subroutines included in the documentation.

Areas of Agreement / Disagreement

The discussion does not appear to reach a consensus, as participants are exploring different aspects of using the Gibson-Ashby model and addressing technical challenges without resolving the underlying issues.

Contextual Notes

Participants mention specific software versions and tools (Visual Studio 2015, Fortran compiler) but do not clarify the dependencies or assumptions related to the setup of user subroutines in Abaqus.

TL;DR
Gibson-Ashby model, Polyurethane foam, mechanical properties
Hello together,

I need help for my bachelor thesis. We want to simulate the mechanical properties of polyurethane foam using the Gibson-Ashby model in Abaqus. So I would like to know if there is a library or something similar for Abaqus. I'm fairly new to Abaqus and the Gibson-Ashboy model, so any help would be greatly appreciated.

Many Thanks

Check the Abaqus Theory Guide chapter "Models for crushable foams" and see if these models fit your needs.

Hello together,

I would like to simulate a tensile test of a polyurethane sample in Abaqus for my bachelor thesis. I will use a Gibson-Ashby material model, assuming that the material will behave linearly elastic. Accordingly, I wanted to use the UMAT subroutine, but unfortunately I can't get it to run.
After I start the job, I get the error "Problem during compilation". Visual Studion 2015 and the Fortran compiler are installed.

Can you help me further ? Thank you and best regards

Setup for Abaqus subroutines is quite tricky, check if you can run any analyses with subroutines included in the documentation chapter Verification --> User Subroutines --> User subroutine verification.
