摘要：

A numerical model for large deflection, elastoplastic analysis of cylindrical sheel structures under air blast loading conditions is presented. The model is based on a transversely-curved finite strip formulation and is capable of stimulating nonlinear transient behaviour of isotropic and stringer-stiffened shells. An implicit time integration scheme and a Newton-Raphson solution technique is employed with a consistent elastoplastic integration algorithm. Numerical verifications of the formulation are carried out by modelling various types of structures under dynamic loadings and comparing the results obtained with other available predictions or experimental results. It is observed that the present model with only one bending mode in the strip direction can predict nonlinear transient response of practical structures with good engineering accuracy.
