A New Endochronic Elasto-Plasticity Approach for Fatigue Crack Growth
A new endochnonic elasto-plasticity approach to analyze fatigue crack growth under general spectrum loading is presented. The endochronic theory incorporated in the present analysis can express accurately plastic strains under cyclic loading. A thin rectangular plate with a central crack and under uniform stresses, in a direction normal to the crack-axis at the edge of the plate is studied. Pure mode I for zero-to-tension cyclic loading is considered. Stress and strain singularities, when the fatigue crack tip passes by, are presented and discussed.
