Evaluation of the dynamic strength of cylindrical and conic matrices of finite length for stamping by high explosives

The equations of two-dimensional dynamic theory of elasticity are used to study the domain of applicability of engineering one-dimensional analytic procedures developed earlier for the evaluation of the dynamic strength of cylindrical and conic matrices of finite length both with free and fastened ends subjected to stamping by high explosives. It is shown that, in view of the "buildup" effect leading, in some cases, to the violation of strength of the matrix, these procedures should be supplemented with correcting calculations performed according to the two-dimensional model for large periods of time. We propose new procedures of design-basis and verifying analyses for cylindrical and conic matrices of finite length subjected to stamping by high explosives. [Material: 30KhGSA].
