摘要：

A strict approach is proposed to analyze the stress intensity factors (SIFs) in an isotropic medium containing plane parallel cracks. The approach implies using a generalized periodic structural model and reducing the boundary-value problems formulated based on this model to a linear system of algebraic equations. An asymptotic analysis of the stress field near the crack apex is carried out, and the exact expressions for the SIF are obtained in the form of series. Numerical results that illustrate the effect of crack arrangement on the SIFs are presented and compared with known approximate theories.
