ABSTRAKT

The model of damage accumulation and the model of degradation of the mechanical properties of layered composites due to the defects of the type of transversal cracking and interlayer cracks have been developed. An analysis of the increase in the defectiveness is made, and the model of degradation of properties is suggested. An algorithm of the refinement of the stress-strain state with account for the increase in the defectiveness is presented; its implementation is possible with the use of the finite-element method.
