Fundamental Fracture Mechanics Equation of Material

Materials Science 2013-06-13 v1

Abstract

On the basis of energy conservation law an without utilizing Linear Fracture Mechanics (LFM) postulates the equation of a real-structure material elastic-plastic fracture has been derived. With the help of this equation the force and energy criteria of Non-linear Fracture Mechanics (NLFM) have been found. These criteria constitute the basis of modern strength analysis of machineparts and structures made of real-structure materials. KlcK_{lc} dependence on ultimate strength limit, yield limit and impact toughness has been established and experimentally confirmed for a number of steels
