Essay

The thesis is devoted to the study of deformed state of two-dimensional viscoelastic bodies containing cracks with failure zones as well as to the slow crack growth in viscoelastic orthotropic media. Semi-analytical method for the investigation of deformed state of a cracked body is presented. Influence of failure zones which are formed in front of the crack tip is taken into account by introducing the cohesive zone model. The model provides the finite stress condition and allows ascribing all non-linear effects of deformation to the cohesive zone.
