摘要
通过对圆管侧向撞击实验 ,证实变形包括撞击处的局部变形和圆管的整体弯曲 ,采用刚塑性假定 ,分别得出了两种变形的计算模式 ,其计算值与实验值吻合得较好 。
The experimental survey of circular tubes under lateral impact demonstrate that its deformation includes local denting and bending deformation.Two calculated models of deformation are presented based on rigid plastic theory ,the calculated results agree well with experimental ones,and the damage degree of circular tubes under lateral impact is well predicted.
