摘要
对一端夹支、一端固支在阶跃载荷作用下弹塑性杆的动力屈曲进行了理论分析和数值计算。用Matlab对控制方程进行数值求解,给出了临界载荷与临界长度的关系,研究了强化模量对临界屈曲载荷的影响。
The dynamic buckling of an elastic-plastic column with one end cliped and another fixed under me step load is studied with theoretical analysis and numerical computation. The relationship between critical buckling load and critical buckling length is given by numerical solution of governing equations. The influence of different hardening modulus on critical buckling load is discussed.
