线性强化材料空间杆系弹塑性分析

Elasticplastic analysis for the linearly hardening structure ofbars joined to a fixedpoint rigid body

将材料的应力-应变关系描述为线性强化模式,推导出了铰接于定点运动刚体上的线性强化材料空间杆系结构应力-应变计算的普遍表达式,给出了计算刚体角位移的非线性方程组,编制了通用程序,计算准确方便,使这一问题得到了圆满的解决。

The linearly hardening function is used to represent the stressstrain relation material. The universal expression about the stress and strain analysis in the linearly hardening structures of bars joined to a fixedpoint rigid body has been derived. The nonlinear equations of calculating the angular displacement of the rigid body have been given and the general program has been worked out. This method is precise and convenient for computing. The problem has been solved satisfactorily.
