An optimal strength design of the wound pressure vessel considering nonhomogeneous temperature field

Abstract

The article presented deals with the optimal strength design of the high pressure compound vessel of mixed construction consisting of the matrix, frequently made of WC–Co, supporting steel ring and outer wound ribbon part. The nonhomogeneous temperature field is taken into account. In the most dangerous working state under the full loading the maximum equivalent stresses at all components equal the corresponding design stresses. The effective stress distribution at the wound part is uniform. A set of equations was derived to calculate all vessel radii as well as the contact pressures.
