Modelling contacts with a total Lagrangian material point method

The total Lagrangian Material Point Method (TLMPM) is an efficient formulation of the well known Material Point Method (MPM). Unlike the MPM, it is not subject to cell-crossing instabilities or numerical failure, and features better quadrature. However, the TLMPM is unable to model (no-slip) contacts seamlessly as the standard updated Lagrangian MPM. This paper presents a contact algorithm for the TLMPM able to model contacts with or without...
