On Stable Crack Growth at Large Scale of Yielding
An investigation of stable crack growth is carried out assuming a line shaped process region. The development of the process region before and during stable crack growth up to the limit of instability is investigated. Different hardening rates and different decohesive stresses at the process region are considered. At large cracks stable crack growth precedes global instability, whereas such crack growth is rather limited or even possibly even at small cracks.
