Fraunhofer Institute for Mechanics of Materials IWMThoMat computational software tools are available for the application within FEM for the commercial software Abaqus and Ansys, for Windows and Linux. The tools are compiled for the respective releases of Abaqus and Ansys.
For the commercial finite element software Abaqus, a compiled user material subroutine for cyclic viscoplasticity and compiled post-processing tool for the lifetime estimation are available. The post-processing tool accesses the Abaqus output database .odb, reads the temperature-stress-inelastic strain-history, and then computes and writes the estimated lifetime and further quantities of interest for the finite elements to the Abaqus .odb file.
For the commercial finite element software Ansys, a compiled user material subroutine for cyclic viscoplasticity and several options for compiled post-processing tools for the lifetime estimation are available. In total, three different tools are available for the lifetime estimation which include a user subroutine to read and write the temperature-stress-inelastic strain-history from the Ansys .rst file to an .ascii file, plus a post-processing tool for the lifetime estimation and an Ansys Customizing Tool (ACT) for the visualization of the estimated lifetime and further quantities of interest for the finite elements in Ansys Workbench.
