Abstract
A review of theoretical developments in predicting the buckling response of cylinders subject to impulsive loads is presented. Most of this theory deals with axisymmetric, radial impulses on cylinders. The development of solutions for the critical modes and loading magnitudes which produce excessive growth of displacements are reviewed. Existing theories cover the specific cases of either entirely elastic or entirely plastic material behaviour for infinite length and short cylindrical shells. The resultant theories are applied to various shell geometries to investigate influencial parameters. A review of numerical finite element and finite difference studies which investigate dynamic pulse buckling is also given. The requirements to examine dynamic buckling of more complex structures such as ring stiffened cylinders are discussed.
