Essay

Methods of strength and durability estimation for composite thin shelled elements of complicated shape structures with cracks and technological defects, which include anisotropic materials main fracture and strength criteria, have been developed. Methods of limit load estimation for plates with holes and cracks have been developed with the account of anisotropy of strength properties of the material. New approach to determination of the shape of holes with low level of stress concentration, which is reduced to the solution of the nonlinear programming problems, is offered. Methods of durability estimation for composite plate-like structural elements based on the study of the fatigue crack growth process along curved paths have been developed.
