摘要
本文采用理想弹塑性模型建立起压杆失稳后的曲率和载荷的关系式,应用摄动法求解压杆的弹塑性大变形,分析了压杆承载能力与塑性区域的关系。
In this paper, the relationship between the curvature and the load after initial buckling of a strut is built up by using ideal elastic - plastic model. Then the large elastic - plastic deflectoin of the strut is determined and its load-carrying capacity due to the development of the plastic region is analysed by using perturbation method.
