Nonlocal Stress Field at Griffith Crack.

Abstract

By means of nonlocal elasticity theory, the Griffith crack problem is solved to determine the state of stress in a plate weakened by a line crack. The maximum stress is found to be finite and occurs away from the crack tip. Cohesive stress is estimated and compared with the calculations based on atomic lattice theory. (Author)
