Abstract
Aluminium specimens of pre-caused defects are tensile tested at different temperatures. The defects are differently oriented to the tensile axis. The results have undergone statistical processing integrated with 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 strength history of loaded defect metal.
