ansys粘塑性材料anand本构方程应用的仿真
|
|
大家好，这是我的程序，目的就是拿一个模型给它加循环温度载荷，从120降到-40再升到120，就这样一直循环3次，我也设置了Anand本构方程参数，但进入post26看出应变方面就只有弹性形变，而塑性形变没有得出，不太清楚为什么，希望大佬们能够给点意见，谢谢： FINISH /FILNAME,EXERCISE1 /PREP7 ET,1,PLANE182 ！定义单元类型 KEYOPT,1,3,2 MPTEMP,1,0 ！定义材料 MPDATA,EX,2,,330e3 MPDATA,PRXY,2,,0.24 MPDATA,ALPX,2,,5.6e-6 MPTEMP,1,0 MPDATA,EX,3,,103.42e3 MPDATA,PRXY,3,,0.3 MPDATA,ALPX,3,,17e-6 MPTEMP,1,0 MPTEMP,2,100 MPDATA,EX,1,,54.05e3 MPDATA,EX,1,,34.75e3 MPDATA,PRXY,1,,0.4 MPDATA,PRXY,1,,0.4 MPTEMP,1,0 MPTEMP,2,100 MPDATA,ALPX,1,,21.85e-6 MPDATA,ALPX,1,,23.889e-6 TB,RATE,1,1,9,9 !TBTEMP,0 TBDATA,1,39.09,89006,22300,6,0.182,3321.15 TBDATA,7,73.81,0.018,1.82,,, RECTNG,0,0.030,0,0.003 RECTNG,0,0.020,0.003,0.0033 RECTNG,0,0.020,0.0033,0.0036 RECTNG,0,0.021,0.0036,0.0046 RECTNG,0,0.020,0.0046,0.0049 AGLUE,ALL FLST,5,3,5,ORDE,2 !定义单元材料材料属性 FITEM,5,7 FITEM,5,-9 CM,_Y,AREA ASEL, , , ,P51X CM,_Y1,AREA CMSEL,S,_Y !* CMSEL,S,_Y1 AATT, 3, , 1, 0, CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* CM,_Y,AREA ASEL, , , , 10 CM,_Y1,AREA CMSEL,S,_Y !* CMSEL,S,_Y1 AATT, 2, , 1, 0, CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* CM,_Y,AREA ASEL, , , , 6 CM,_Y1,AREA CMSEL,S,_Y !* CMSEL,S,_Y1 AATT, 1, , 1, 0, CMSEL,S,_Y CMDELE,_Y CMDELE,_Y1 !* FLST,2,5,5,ORDE,2 ！画网格 FITEM,2,6 FITEM,2,-10 AESIZE,P51X,0.0005, MSHAPE,0,2D MSHKEY,0 !* FLST,5,5,5,ORDE,2 FITEM,5,6 FITEM,5,-10 CM,_Y,AREA ASEL, , , ,P51X CM,_Y1,AREA CHKMSH,'AREA' CMSEL,S,_Y !* AMESH,_Y1 !* CMDELE,_Y CMDELE,_Y1 CMDELE,_Y2 !* FINISH /SOL ！进行瞬态设置 ANTYPE,4 timint,off NLGEOM,on LSEL,S,LOC,X,0 DL,ALL,,SYMM NSEL,S,LOC,X,0 NSEL,S,LOC,Y,0 D,ALL,,0,,,,UY,,,,, ALLSEL,ALL TREF,28 TOFFST,273 TUNIF,1E-5 CNVTOL,F,,,,0.001 NSUBST,20 !autots,off PRED,ON TUNIF,120 ！加循环载荷 TIME,180 SOLVE TUNIF,100 TIME,270 SOLVE TUNIF,80 TIME,360 SOLVE TUNIF,60 TIME,450 SOLVE TUNIF,40 TIME,540 SOLVE TUNIF,20 TIME,630 SOLVE TUNIF,0 TIME,720 SOLVE TUNIF,-20 TIME,810 SOLVE TUNIF,-40 TIME,900 SOLVE TIME,990 SOLVE TUNIF,-20 TIME,1080 SOLVE TUNIF,0 TIME,1170 SOLVE TUNIF,20 TIME,1260 SOLVE TUNIF,40 TIME,1350 SOLVE TUNIF,60 TIME,1440 SOLVE TUNIF,80 TIME,1530 SOLVE TUNIF,100 TIME,1620 SOLVE TUNIF,120 TIME,1710 SOLVE TIME,1800 SOLVE TUNIF,100 TIME,1890 SOLVE TUNIF,80 TIME,1980 SOLVE TUNIF,60 TIME,2070 SOLVE TUNIF,40 TIME,2160 SOLVE TUNIF,20 TIME,2250 SOLVE TUNIF,0 TIME,2340 SOLVE TUNIF,-20 TIME,2430 SOLVE TUNIF,-40 TIME,2520 SOLVE TIME,2610 SOLVE TUNIF,-20 TIME,2700 SOLVE TUNIF,0 TIME,2790 SOLVE TUNIF,20 TIME,2880 SOLVE TUNIF,40 TIME,2970 SOLVE TUNIF,60 TIME,3060 SOLVE TUNIF,80 TIME,3150 SOLVE TUNIF,100 TIME,3240 SOLVE TUNIF,120 TIME,3330 SOLVE TIME,3420 SOLVE save finish |
