Modeling and Analysis of Crack Initiation in a Cylindrical Specimen
Abstract: In an engineering component subjected to variable loading/cyclic stressing, the stress and stress state, particularly the plastic strain and the triaxiality, play an important role in determining its life. Ductile materials predominantly fail by void growth, and crack initiation in ductile material can be associated with a specified volume of voids. Estimation of this crack initiation life and the remaining life through analytical modeling and comparing it through experimental testing …
