Abstract

The problem of finding an equally strong hole form in the crack tip and its influence on the development of a crack are considered. A criterion and method for solving the problem of preventing the brittle fracture of a body weakened by a longitudinal shear crack are proposed. The condition for brittle fracture is obtained.

 

Keywords: crack, longitudinal shift, optimal hole, principle of equal strength
