摘要
本文详细分析了爆炸载有作用下固支加筋方板的大挠度塑性动力响应，给出了各种可能的运动模式以及相应的判别条件，导出了最大残余变形的计算式，与文献［３］的试验结果比较表明，在多数情况下符合良好．
The large deflection dynamic plastic response of fully clamped square plates with stiffeners under blast led is analyzed in detail in this peper. Various relevant motion patterns and criterions are presented.The formulas of maximum permanent deformation of the plates with stiffeners are derived.The results of calculation are compared with those of experiment in [3],with good agreement shown in most cases.
