摘要
这种近似机动法,即先假定某个运动许可的塑性应变率循环,然后根据运动安定定理的有关公式来估算真实的破坏载荷系数。并以一个双跨连续梁作用循环载荷为例,对此方法的应用进行了说明。
An approximate kinematical method for solving the shakedown problems is presented in this paper. The scheme adopted is firstly to assume a kinematically admissible plastic strain rate cycle. Then, the actual collapse load factor is estimated according to some relevant formulae of the kinematical shakedown theorem. Application of the approximate kinematical method is exemplified using a continuous two-span beam applied with cyclic load.
