我不知道是否你需要的
B.2.15. Strain Rate Dependent Plasticity??? Example: 4140 Steel
MP,ex,1,209e9 ! Pa
MP,nuxy,1,.29 ! No units
MP,dens,1,7850 ! kg/m3
TB,PLAW,,,,5
TBDATA,1,1 ! LCID yield stress vs. strain rate (see first EDCURVE command below)
TBDATA,2,22e5 ! Tangent modulus (Pa)
TBDATA,3,2 ! LCID Elastic modulus vs. strain rate (see second EDCURVE command below)
*DIM,StrnRate,,5
*DIM,YldStres,,5
*DIM,ElasMod,,5
StrnRate(1) = 0,.08,.16,.4,1.0
YldStres(1) = 207e6,250e6,275e6,290e6,300e6
ElasMod(1) = 209e9,211e9,212e9,215e9,218e9
EDCURVE,ADD,1,StrnRate(1),YldStres(1)
EDCURVE,ADD,2,StrnRate(1),ElasMod(1) |
