Development of numerical simulation in solidification processing of continuous casting 增量变刚度法在铸件凝固过程数值模拟中的应用
When the method of incremental variable stiffness is used in the plastic analysis , the loads are applied sequentially . once the plastic hinge is formed , the loads are increased . so the whole process is divided into many stages 在塑性分析中主要采用增量变刚度法,荷载是逐级施加的,以每形成一个塑性铰为分界点,把整个加载过程分成若干个阶段
