Kopsavilkums

A detailed finite-element analysis of the stress-strain state in the load transfer zone of uneasily tensioned flat test specimens made of a high-strength unidirectional carbon fiber-epoxy composite is carried out with account of the elastoplastic behavior of a structural polyurethane adhesive. Various schemes of introduction of external loads into the specimens are considered. A numerical finite-element analysis of different configurations of specimen tabs allowed us to put forward a technique for significantly reducing the dangerous concentration of operating stresses.
