The moving friction cone approach for three-dimensional contact simulations

A finite element contact approach based on the Moving Friction Cone (MFC) formulation is presented herein. The formulation is based on the contact constraint described using a single gap vector. Such a simplification, in comparison with the standard approach where normal and tangential gap vectors are used, enables significantly simpler, shorter and faster element code. The penalty formulation is described in the Lagrangian form what enables large deformations and displacements. A triangular contact element is developed using a high abstract mathematical level of symbolic description. Thus enabling a consistent linearisation, quadratic rate of convergence, algorithmic robustness, fast evaluation time, as well as a compact element code.
