Description
Processing of structural materials usually involves interactions between multiple physical phenomena which influence the material microstructure and properties. Understanding the connection between processing conditions, microstructure, and material properties is a costly process. It is therefore the aim of Integrated Computational Materials Engineering (ICME) to establish processing-microstructure-property relationships with the help of computer simulations. The Düsseldorf Advanced Material Simulation Kit (DAMASK) 1, an open source, multi-physics crystal plasticity software, is a simulation platform with the capability and flexibility to perform and analyze complex multi-field simulations. Its modular structure allows for solving of different field equations, for example, mechanical, thermal & damage equations using Fast Fourier Transform (FFT) and Finite Element (FE) based solvers provided by the PETSc numerical library 2,3,4. The pre- and post- processing of DAMASK facilitates coupling with other platforms such as DREAM.3D, MTEX, Neper, Gmsh, and Paraview 5. The use of HDF5 output 6 and the DAMASK Python library have made analysis and visualization of results easier, faster, and more memory efficient as compared to storing the output in ASCII format.
Here, we present a workflow, integrating multiple simulation tools to demonstrate the use of DAMASK in simulating real world material processing applications.
