โœฆ Synopsis

We consider a crack in a linearly varying held of normal stress that is kept constant, and apply shearing tractions that increase with time. This leads eventually to slip progressing into the closed part of the crack. If the crack lies entirely in the compressive part of the normal stress field, the problem can be solved in closed form, and it is easy to get results also for shearing tractions that start to decrease and eventually lead to backslip.

A contact enforcement algorithm has been developed for matrix-free quasistatic finite element techniques. Matrix-free (iterative) solution algorithms such as non-linear conjugate gradients (CG) and dynamic relaxation (DR) are desirable for large solid mechanics applications where direct linear equat
