A viscoplastic theory of dynamic buckling is developed for cylindrical shells subjected to uniform radially inward impulses. The influence of the yield function nonlinearity and elevated temperature on the magnitude of displacements, buckling mode, and threshold impulse is investigated. Asymmetrical and axisymmetrical modes of buckling are considered. The asymmetrical mode is proved to exist. The obtained theoretical results are compared with existing experiments.
