Behavior of Shells Made of Composites during the Dynamic Application of Axian Compression

摘要

In nonlinear formulation we examine the problem of the dynamic stability of cylindrical shells made of composites, e.g., glass reinforced plastic, under dynamic axial compression. We assume as given the law of mutual displacement of the ends of the shell. Using the Bubnov-Galerkin method, the equations of the nonlinear theory of shells in partial derivatives are reduced to ordinary differential equations with aperiodic coefficients. The equations obtained were integrated numerically using a BESM-2M computer for various loading rates and shell parameters relative to certain brands of glass-reinforced plastics. Similar problems for isotropic metal shells have been examined previously 1, 2. The case of dynamic application of external pressure to an orthotropic shell was examined. Russian translations. (mgm)
