Abstract
In the framework of a model for the quasistatic crack growth in pressure sensitive
elasto-plastic materials in the planar case, we study the properties of the length l (t) of the crack as a function of time. We prove that, under suitable technical assumptions
on the crack path, the monotone function l is a pure jump function.
