In calculation, adopted load-unload criterion of stress wave propagation was to decide load-unload state of element and to adjusts and transfers internal stress for tensile failure element as well.
计算中用应力波传播的加卸载判别准则来决定单元的加卸载状态，对受拉破坏单元进行内部应力调整和应力转移。
So, how to convert the number of load data to the internal force and stress data of structural member are necessary and in urgent.
因此，如何快速地将如此庞大的载荷数据转化为结构杆件的内力和应力数据既十分必要又迫在眉睫。
