ansys滞回分析

用ANSYS可以实现结构的滞回分析，这在地震反应分析等多个方面很有用处，下面是一个简单的命令流，希望对大家有所启发。FINI/CLEAR/PREP7!定义单元类型，实常数，材料特性ET,1,SHELL143R,1,12,,,,,MP,EX,1,210000MP,NUXY,1,0.3!双线性随动强化模型TB,BKIN,1,1,2,1TBDATA,,310,600,,,,!定义关键点、线、面K,1,54,0,0K,2,-54,0,0K,3,54,0,1000K,4,-54,0,1000A,1,2,4,3!定义边界荷强迫位移,划分网格AESIZE,ALL,27,MSHAPE,0,2DMSHKEY,0CM,_Y,AREAASEL,,,,1CM,_Y1,AREACMSEL,S,_YAMESH,_Y1*DO,I,1,5D,I,ALL,0*enddo!指定求解结果的输出项目OUTPR,BASIC,ALLOUTRES,ALL,ALL!分为4个荷载步进行求解!第1荷载步D,46,ux,60TIME,1AUTOTS,0NSUBST,10,,,1KBC,0LSWRITE,01,!第2荷载步D,46,ux,-60TIME,3AUTOTS,0NSUBST,20,,,1KBC,0LSWRITE,02,!第3荷载步D,46,ux,60TIME,5AUTOTS,0NSUBST,20,,,1KBC,0LSWRITE,03,!第4荷载步D,46,ux,-60TIME,7AUTOTS,0NSUBST,20,,,1KBC,0LSWRITE,04,!求解FINISH/SOLULSSOLVE,1,4,1,!画出荷载位移曲线FINISH/POST26NSOL,2,46,U,XRFORCE,3,46,F,XXVAR,2PLVAR,3
