Peridynamic Processor
Analysis software to perform 3D peridynamic simulation of laminated composites under static and dynamic loads.
About
The Peridynamic Processor is a peridynamics based innovative tool to analyze progressive damage in composite materials. It is written in Python and Cuda version of C++. PDP can model damage due to fiber-matrix debonding, fiber breakage, and delamination. Additionally, it can also model impact damage in composite materials due to rigid impactors of any arbitrary shape hitting the material at any arbitrary orientation. This allows PDP to model compression after impact problems as well.

PDP is based on the peridynamic formulation specifically developed for modeling orthotropic materials. This formulation is expanded to consider complex problems in composite laminates, subjected to static, dynamic, and impact loadings, that are difficult to be addressed via finite element analysis. The three main functions of the program are the Preprocessor, Solution, and Postprocessor. Within the preprocessor, solution input files can be generated by the user. With every added attribute, 2D and 3D visualizations are updated to reflect the changes. While the solution is running, the output results may be plotted in real-time using the built-in features.
