我在ANSYS钢筋混凝土非线性分析中出现材料本构关系的错误
错误如下
*** FATAL *** CP = 2062.453 TIME= 13:19:43
The supplied nonlinear material properties produced an incorrect
material tangent matrix.Please check your TB input carefully.A
very small yield stress may cause this failure.
上面显示材料的本构关系模型的有问题,可我觉得没有问题啊
下面是我本构关系的命令流:
定义混凝土本构模型
FC=23.1e6 单轴抗压强度
FT=1.89e6
tb,concr,1 混凝土破坏准则W-W5参数
tbdata,0.2,0.95,FT,-1
tb,miso,1,11 混凝土应力应变曲线,用MISO模型
tbpt,0.0002,fc*0.19
tbpt,0.0004,fc*0.36
tbpt,0.0006,fc*0.51
tbpt,0.0008,fc*0.64
tbpt,0.001,fc*0.75
tbpt,0.0012,fc*0.84
tbpt,0.0014,fc*0.91
tbpt,0.0016,fc*0.96
tbpt,0.0018,fc*0.99
tbpt,0.002,fc
tbpt,0.0033,fc
mp,ex,2,2.0e11 贯穿钢筋
mp,prxy,2,0.3
mp,dens,2,7850
tb,bkin,2 贯穿钢筋的应力应变关系,用BKIN模型
tbdata,300e6,0
已经一个星期了,没找到错误在哪,马上就要交报告!
