Abstract

The present paper is devoted to the solution of the 3-D fracture mechanics problem for linearly elastic, homogeneous and isotropic solid with two coaxial penny-shaped cracks under normally incident harmonic tension-compression wave with allowance for the contact interaction of cracks’ adjoining faces. The dependence of the normalized stress intensity factor (opening mode) versus the mutual arrangement of cracks is studied. The present numerical results are compared with corresponding those obtained without allowance for the contact interaction of cracks’ faces.
