摘要

将量纲分析方法引入圆形板基本动力控制方程，提出了一种新的无量纲数，用于分析水下爆炸荷载作用下夹紧圆形板的动态塑性变形。基于大量水下爆炸试验数据，建立了圆板无量纲最终塑性变形与新的无量纲数之间的关系。同时，与另外两个已发表的无量纲参数进行了对比分析，表明本文提出的新无量纲数对水下爆炸条件下圆板的动塑性响应预测更为有效和广泛。

A new dimensionless number for dynamic plastic deformation analysis of clamped circular plates subjected to underwater blast loading

A new dimensionless number is proposed for dynamic plastic deformation analysis of clamped circular plates under underwater explosion loads by introducing dimensional analysis method to the basic dynamical governing equations of circular plates. The relation between dimensionless final plastic deformation of circular plates and the new dimensionless number is established based on massive underwater explosion test data. Meanwhile, comparative analysis was discussed with two other published dimensionless parameters which indicated the new dimensionless number proposed in this paper is more effective and extensive to predict the dynamic plastic response of circular plates under underwater explosion condition.
