Stress-intensity factor solutions for embedded elliptical cracks in round bars subjected to tensile load

In this paper, stress-intensity factor solutions are presented for an embedded elliptical crack in a round bar subjected to tensile load. The factors (SIF) tabulated form and were obtained from three-dimensional finite-element analyses of configuration. provide the as function three dimensionless parameters representative size, aspect ratio flaw its relative position cross section. cover ranges that allow most internal shapes practice be considered. order validate numerical model developed, some particular cases compared with flaws different geometries available literature. Afterwards, sequential methodology fatigue growth is presented, including conditions recategorization semi-elliptical surface crack. A comparison predicted paths experimental results propagation initiated defects bars also presented. This validation shows capability proposed SIF study geometry.
