   Abstract:
   The convected description is introduced for finite deformation frictional contact problems, such that both Coulomb and more general friction criteria can be conveniently and reliably numerically implemented in Lagrangian finite element calculations. The discussion includes careful definition of the convected frame from the standpoint of differential geometry, complete with physical interpretations of the frame and the associated slip and traction rate measures. As result, the work provides a sound mathematical and continuum mechanical foundation for future implementations of general friction laws in large deformation solid mechanics computing architectures.
