Contact Structural Mechanics Application

The Contact Structural Mechanics Application contains the contact mechanics implementations that can be used by the Structural Mechanics Application within Kratos Multiphysics.

Solution Solution Solution Solution Solution Solution

The application includes tests to check the proper functioning of the application

Features:

  • Mesh tying conditions based in mortar formulation

  • Augmented Lagrangian contact conditions based in mortar formulation

    • Frictionless formulation

    • Frictional formulation

  • Penalty contact conditions based in mortar formulation

    • Frictionless formulation

    • Frictional

  • Simplified MPC conditions based in mortar formulation. With the mortar formulation the weight are computed, allowing to compute a Simplified NTN and a simplified NTS

    • Frictionless formulation

    • Frictional formulation

    • Mesh tying formulation, with tension checking

  • Self-contact compatible

  • Strategies, processes, solvers and convergence criterias used by the contact formulation

  • Several strategies for adaptive remeshing

  • The application includes search utilities in order to create the contact conditions

  • Frictional laws (WIP) in order to consider different types of frictional behaviour

  • +115 Python unittest, including Validation tests, and +85 cpp tests

Examples:

Examples can be found here, and here for several contact adaptive remeshing examples
