Abstract
Abstract
Calculation models are developed to examine dynamic stress concentration and fracture in a plane elastic fiber-reinforced composite sheet. The sheet consists of a regular system of alternating extensible fibers and pliable adhesive layers. In calculations, special algorithms are built preventing or minimizing parasite distortions caused by the mesh dispersion. Two engineering models of the adhesive are considered: (i) inertionless bonds of constant stiffness, and (ii) an inertial medium perceived shear stresses. Clarified solutions of the problem are obtained in the case that the sheet pre-stretched along fibers.
