EFFECT OF DEFECT ORIENTATION ON METAL FRACTURE - STATISTICAL PROGNOSIS

Aluminium specimens of pre-caused defects are tensile tested at differ ent temperatures. The defects are differently oriented to the tensile axis. The results have undergone statistical processing integrated wit h fundamental fracture approach. Analytical model to prognosticate the metal reliability in the range of applied tensile stresses is found. A method for evaluation of the defects orientation effect on fracture is suggested. The introduced strength spaces present a principal stren gth history of loaded defect metal.
