Description

This paper is concerned with the tension of infinite solids containing a doubly-periodic array and a zig-zag array of cracks. We define suitable unit regions, assume the stress potentials as eigen function expansions, and determine the unknown coefficients from the boundary conditions of the used unit regions. Numerical results of the stress intensity factors, the crack opening displacements and the longitudinal stiffnesses of the cracked solids are given for various values of the parameters, and they are fitted by reliable formulae for convenience of engineering applications.
