摘要：

A short review of investigations on the counterintuitive behavior of impulsively loaded structural elements is given. Counterintuitive behavior (CIB) is an appearance of final deflections of these elements which is contrary to the direction of the impulsive loading. Some results of different plates and caps subjected to blast loading are described. These results show a possibility of CIB of plates and shallow shells. This effect can be accompanied by a Failure of structural elements. The experimental data are discussed with the help of different theoretical results and models of the aerodynamics and structural dynamics. Copyright (C) 1996 Elsevier Science Ltd.
