To obtain more precise prediction of dynamic deformation, theoretical analysis and experimental investigations were carried out on the plasticity dynamic response of clamped square plates subject to underwater explosion loading in a water tank. Based on the principle of the energy equilibrium, the more reasonable deductive expressions were obtained for the final deflections of the shock wave upon the built-in plates subjected to the impulse loading, and the maximum large plasticity deformation solution were also obtained by the analytical plasticity method of equal-moment calculation. The different plastic deformations of the plates were measured for different charge weights and propagating distances. Both of the deformation displacements of test and theoretical calculation are quite agreement to within an about 10% discrepancy.

分析研究了在装药水中爆炸产生的强冲击载荷作用下固支方板的塑性动力响应过程。通过对水中爆炸理论和板的大变形理论分析,应用能量原理和Lagrangian函数,推导出反映固支方板在冲击载荷作用下变形的最终挠度的解析解。水中爆炸对固边方板破坏的实验在自制的水箱中进行。对不同的装药重量和炸距情况下方板的变形情况进行了理论计算,并对实验结果和误差来源进行了分析。实验结果和理论结果具有较好的一致性。

分析研究了在装药水中爆炸产生的强冲击载荷作用下固支方板的塑性动力响应过程。通过对水中爆炸理论和板的大变形理论分析,应用能量原理和Lagrangian函数,推导出反映固支方板在冲击载荷作用下变形的最终挠度的解析解。水中爆炸对固边方板破坏的实验在自制的水箱中进行。对不同的装药重量和炸距情况下方板的变形情况进行了理论计算,并对实验结果和误差来源进行了分析。实验结果和理论结果具有较好的一致性。

水下爆炸  /  固支方板  /  塑性大变形  /  等冲量分析

To obtain more precise prediction of dynamic deformation, theoretical analysis and experimental investigations were carried out on the plasticity dynamic response of clamped square plates subject to underwater explosion loading in a water tank. Based on the principle of the energy equilibrium, the more reasonable deductive expressions were obtained for the final deflections of the shock wave upon the built-in plates subjected to the impulse loading, and the maximum large plasticity deformation solution were also obtained by the analytical plasticity method of equal-moment calculation. The different plastic deformations of the plates were measured for different charge weights and propagating distances. Both of the deformation displacements of test and theoretical calculation are quite agreement to within an about 10% discrepancy.
