A new probabilistic model of fatigue crack growth is constructed in which the parameters are explicit functions of the stress intensity factor. There are two versions of this model. These models are applied to a set of fatigue crack growth data. Some comments are offered on the implications of these
An investigation of the autonomy of the process region at the tip of a crack is carried out. An elastic plastic linearly hardening material is assumed. A cohesive zone model with constant cohesive stress is chosen. The cohesive zone length is observed to decrease with decreasing hardening rates and
