A Finite-Element Analysis of Fatigue Crack Closure
TL;DR: In this paper, a two-dimensional finite-element analysis for predicting crack-closure and crack-opening stresses during cyclic loading has been proposed, which accounts for elastic-plastic material behavior and changing boundary conditions associated with crack extension and intermittent contact of the crack surfaces under cyclic load cycling.
