Abstract
We propose a method for the analysis of the limiting state of transversely isotropic plates with surface and internal cracks and obtain a new simple approximate formula for the evaluation of the stress intensity factors. The numerical calculations are based on the improved version of the analysis of stress-strain states in defect-free transversely isotropic plates. The failure is initiated as soon the damage ratio near the crack front in the direction of crack propagation attains a certain critical value.
