Peridigm User Material Interface Dataset

The dataset includes a Fortran user material routine which is used for a reference finite element and peridynamic model of a dogbone. The user material interface allows the simplified use of already existing material routines in the peridynamic framework Peridigm. The interface is based on the Abaqus UMAT definition and allows the integration of these Fortran routines directly into Peridigm. The integration of UMAT routines based on finite elements in Peridigm eliminates the need for parallel development of existing material models from classical continuum mechanics theory. Thus, all developer of material models can utilize both finite element frameworks and Peridynamics. This opens up new possibilities for analysis, verification and comparison. In order to be able to use the material routine, the UMAT file must be precompiled and copied to a specific folder. With this interface many material routines can be reused and applied to progressive failure analysis.
