On the pure jump nature of crack growth for a class of pressure-sensitive elasto-plastic materials

Dal Maso, GianniToader, Rodica2021-01-192021-01-192021-01-19https://openscience.sissa.it/handle/1963/35416In 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.enfracture mechanicsplasticityquasistatic evolutionrate-independent problemsOn the pure jump nature of crack growth for a class of pressure-sensitive elasto-plastic materialsPreprint
