Abstract

On the basis of a modified Dugdale model, we investigate the influence of the anisotropy of the material, in particular, differences between the ultimate tensile strength and ultimate compressive strength, on the limit state of an orthotropic plate weakened by a periodic system of periodic collinear cracks under biaxial external loading. As a strength criterion, the Hoffman strength criterion is considered. Strength diagrams of an orthotropic plate with a crack for different strength and crack resistance parameters are obtained.
