A Segment-to-segment algorithm for finite volume mechanichal contact simulations

This paper presents a new segment-to-segment contact algorithm for calculating normal contact force. The proposed algorithm calculates contact force using an integral value of the penetration, which should improve the overall accuracy of the numerical model. The inspiration for such an approach is based on the segment-to-segment contact formulation commonly used in the finite element contact algorithms. The implementation will allow for the calculation of mechanical contact on arbitrary unstructured meshes and large deformation of contacted bodies. The proposed contact algorithm was tested using contact benchmarks that include large deformation and large sliding contact.
