    Fully coupled thermal-stress analysis in Abaqus/Standard- equations

    In Abaqus I really don't see any change in temperature. But in FEniCSx, there is a reduction in temperature in the order of 10^(-2). Which could be due to the couple term. See FEniCSx result: Since the wrong units were implemented in both Abaqus and FEniCSx, they should have given the same...

    Fully coupled thermal-stress analysis in Abaqus/Standard- equations

    Solved the issue. It lied in the fact that I did not scale the units properly. Density had to be in tonne/mm^3 if E-Module is in MPa. Save goes for specific heat capacity and heat conductivity, etc..

    Fully coupled thermal-stress analysis in Abaqus/Standard- equations

    For a purely elastic case, I totally agree with you. But if we include thermoelasticity, then the above mentioned heat conduction equation comes into play. A non-zero strain rate should indeed result in change in temperature, right? This could very well be reversible due to elastic deformation.

    Fully coupled thermal-stress analysis in Abaqus/Standard- equations

    Thanks for the tip on CalculiX, will check it out. As per the heat conduction equation, temperature should change due to a non-zero deformation-rate right? I wonder why Abaqus has just included heat generation due to inelastic deformation.

    Fully coupled thermal-stress analysis in Abaqus/Standard- equations

    Hi, I'm simulating a fully coupled thermal-stress problem with linear elastic material in Abaqus/Standard and comparing the results with my own implementation of the same problem in FEniCSx. The weak form in FEniCSx has been derived using the balance equations mentioned in the paper Farhat et...
