OpenSees RambergOsgoodSteel Material Test

关于 RambergOsgoodSteel Material 材料的信息参考 RambergOsgoodSteel Material。这里也顺便测试一下。 材料参数(Material Parameters) Fy:屈服强度(yield strength); E0:初始弹性模量(initial elastic tangent); a:屈服时残余应变,通常取0.002("yield offset" and commonly used value for a is 0.002); n:控制从弹性段向塑性段过度的参数,同时,当增大n时材料的强化速率会降低,通常取大于等于5(parameter to control the transition from elastic to plastic …
