What is PRISMS-Plasticity?

PRISMS-Plasticity is a Finite Element Method (FEM) code for solving boundary value problems arising in Continuum Plasticity and Crystal Plasticity. It is build on top of the deal.II open source finite element library [http://www.dealii.org]

This code is developed by the PRedictive Integrated Structural Materials Science (PRISMS) Center [http://www.prisms-center.org/] at University of Michigan which is supported by the U.S. Department of Energy (DOE), Office of Basic Energy Sciences, Division of Materials Sciences and Engineering under Award #DE-SC0008637

Installation:

  1. Install deal.II (version 8.4.1 recommended)
  1. Clone the PRISMS Plasticity GitHub repo https://github.com/prisms-center/plasticity

Usage:

Running plasticity applications, for example simple tension boundary value problem with continuum plasticity material model:

  • $ cd applications/continuumPlasticity/simpleTension
    For debug mode [default mode, very slow]:
  • $ cmake CMakeLists.txt -DCMAKE_BUILD_TYPE=Debug
    For optimized mode:
  • $ cmake CMakeLists.txt -DCMAKE_BUILD_TYPE=Release
    and
  • $ make

    Execution (serial runs):
  • $ make run
    Execution (parallel runs):
  • $ mpirun -np nprocs ./main
    [here nprocs denotes the number of processors]

Updates: Since plasticity code is still under active development, regular code and documentation updates are pushed to the upstream repo (https://github.com/prisms-center/plasticity) and we strongly recommend users to synchronize their respective clones/forks at regular intervals or when requested by the developers through the announcements on the mailing list.

Visualization

Output of the primal fields and postprocessed fields is in standard vtk format (parallel:.pvtu, serial:.vtu files) which can be visualized with the following open source applications:

  1. VisIt (https://wci.llnl.gov/simulation/computer-codes/visit/downloads)
  2. Paraview (http://www.paraview.org/download/)

Getting started:

Examples of various boundary value problems are located under the applications/ folder. Easiest way to get started on the code is to run the applications.

Applications are intended to serve as (1) Demonstration of the capabilities of this library, (2) Provide a framework for further development of specialized/advanced applications by users.

Application or code under development/testing is preceded by an underscore.
