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

The article presented deals with the optimal strength design of the high pr essure compound vessel of mixed construction consisting of the matrix, freq uently made of WC-Co, supporting steel ring and outer wound ribbon part. Th e nonhomogeneous temperature field is taken into account. In the most dange rous working state under the full loading the maximum equivalent stresses a t all components equal the corresponding design stresses. The effective str ess distribution at the wound part is uniform. A set of equations was deriv ed to calculate all vessel radii as well as the contact pressures. (C) 1999 Elsevier Science Ltd.
