The article considers the issues related to the dynamic behavior of cylindrical shells of elliptical shape under axisymmetric impulse loading. In the course of the study, the results of numerical modeling of the behavior of layered composite shells of elliptical shape under dynamic axial impact loads were obtained. During the experiment, various sequences of shell layers were used, their behavior was compared under impact loading during different time periods. It is noted that cylindrical shells experience dynamic crushing loads that exceed static ones if their duration is very short compared to the natural period of the system, and less than static crushing load at longer periods. The ratio between dynamic and static crushing loads is of practical importance, since it gives a direct idea of the bearing capacity of shells subjected to sudden loading.
