A model of roughness-induced crack closure

A macrostructural model for simulating the combined effects of roughness and plasticity induced fatigue crack closure

“…Since the pioneering work of Walker and Beevers [1] the RICC mechanism has been widely recognized as an important mechanism of crack closure [3][4][5][6]. RICC has been related to a number of material and loading conditions that affect the size and pattern of the tortuous crack growth path including: the material grain size [7][8][9][10][11][12], the applied stress intensity factor range [7,11,13], alloying particles and phases [10,11,[13][14][15][16], alloy aging [14,17], and crystallographic texture [10].…”
