摘要

The response of re-entry vehicle-type shells to blast loads is investigated and is described in terms of surface loads on the vehicle. Extensive data on both surface pressures and structural response of cylindrical and conical shells are presented. Peak pressure and impulse are identified as the important load characteristics which determine structural response and critical loads are presented in these terms. A theoretical description of dynamic buckling of cylindrical shells subjected to transient surface pressures is given to explain observed modes of failure and to predict critical loads for buckling over a wide range of load and structural parameters.
