摘要
为了预报加筋板结构在爆炸冲击载荷作用下的变形程度,将加筋板的变形分为整体变形和局部变形,借助数值计算拟合了两者能量分配关系,进而提出了爆炸冲击作用下加筋板结构变形的理论计算方法,并与实验结果进行比较,结果吻合较好。
In order to predict the deformation of the stiffened plates under blast loads, the deformation was divided into the whole deformation and the local deformation. With the help of the numerical me- thods the energy distribution relation of them was obtained, based on which a new theory method was proposed. Comparied with the experimental results the method is good enough to be used in the engi- neering.
