Abstract
Aluminium specimens with pre-caused cracks with different tip radii are tensile tested at two temperatures. The cracks are differently oriented to the tensile axis. The results have undergone statistical processing integrated with fundamental fracture approach. Analytical model to prognosticate the defect metal reliability and the reliability of a randomly chosen detail from a defined set in the range of applied tensile stresses is found. A method for evaluation of the cracks tip radii and cracks orientation effect on fracture is suggested. The introduced strength spaces present a principal strength history of defect metal in interval ‘load imposing-fracture’ at different temperatures.
