Ah&act-It has been suggested that the crack closure concept can account for the retardation in crack growth rate following removal of tensile overloads. To test this possibility measurements of effective stress were made on center notched cracked specimens during tests in which tensile overloads wer
Abstrac&-The minimum strain energy density theory, originally developed for crack growth in isotropic solids, is extended to the anisotropic case. The criterion for predicting the direction and onset of crack growth is reformulated through minimization of the ratio of the strain energy density (writ
