Abstract

A new statistical formulation and a relevant experimental approach todetermine the growth rate of microcracks were proposed. The method consists of experimental measurements and a statistical analysis' on thebasis of the conservation law of number density of microcracks in phase space. As a practical example of the method, the growth rate of microcracks appearing in an aluminium alloy subjected to planar impact loading was determined to be ca. 10 mu m/mu s under a tensile stress of 1470 MPa and load duration between 0.26 mu s and 0.80 mu s.
