Delamination Initiation and Optimal Thickness of Reinforcement in Elastic-Plastic Pressure Vessels

Abstract

In the present paper the effects of physical and non-linearities are taken into account their influence on the delamination initiation and limit states of composite pressure vessels reinforcement are discussed. The numerical examples deal with the behavior of the reinforcement of the junction of shells. The optimisation method of the reinforcement thickness is also formulated and solved herein.
