摘要: A new approach to irreversible quasistatic fracture growth is given, by means of Young measures. The study concerns a cohesive zone model with prescribed crack path, when the material gives different responses loading and unloading phases. In particular situation of constant response, result contained in [G. Dal Maso, C. Zanini: Quasi-static for path. Proc. Roy. Soc. Edinburgh Sect. A, 137A (2007), 253–279.] recovered. this case, convergence discrete time approximations improved.
