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.

本数据集包含一套Fortran用户材料子程序，用于哑铃状试样的参考有限元（Finite Element）模型与近场动力学（Peridynamics）模型。

该用户材料接口可在近场动力学框架Peridigm中简化调用现有材料子程序。此接口基于Abaqus UMAT的定义，可将上述Fortran子程序直接集成至Peridigm中。将基于有限元的UMAT子程序集成至Peridigm，无需针对经典连续介质力学理论下的现有材料模型进行并行开发。由此，所有材料模型开发者可同时使用有限元框架与近场动力学方法，为分析、验证与对比工作开辟全新可能。

若需使用该材料子程序，需将UMAT文件预先编译并复制至指定文件夹。借助该接口，大量材料子程序可被复用并应用于渐进失效分析。
