ExplicitSolidDynamics toolkit for OpenFOAM

         

         

1. Introduction

This novel toolkit is based on a cell centred Finite Volume Method to predict large deformation in solids. The governing equations comprise of first order hyperbolic conservation laws for linear momentum and deformation gradient tensor of the system. This helps to bridge the gap between Computational Fluid Dynamics and Computational Solid Dynamics. The governing equations are spatially discretised using a low order cell centred Finite Volume Method along with an upwind Riemann solver.

Key features

• Second order accuracy for velocities and stresses/strains.
• Parallelised C++ implementation within OpenFOAM code.
• Robust methodology with practical applications.
