Hi everyone,

I want to simulate the mechanical behavior of soil with ansys apdl. I have defined the properities of the porous elasticity and the modified cam-clay material according to the help file as:

/prep7

 

mp,ex,1,1e9

! Porous elasticity
Kappa = 0.0024
NU0    = 0.279
pt_el = 5.835
E0    = 0.34 
p0    = 69

TB,PELAS,1,,,POISSON
TBDATA,1, Kappa, pt_el, NU0, E0

! Cam-clay Plasticity
Lambda_F = 0.014
Mc       = 1.24
a0       = 35
ah_min   = 0.35
Beta_Dry = 1
Beta_Wet = 1 
Ks       = 1

TB,SOIL,1,,,CAMCLAY
TBDATA,1, Lambda_F, Mc, a0, ah_min  
TBDATA,5, Beta_Dry, Beta_Wet, Ks

 

However, when I checked the tblist, only the tabular data of the cam-clay material exists. In addition, when I run the analysis, it gives a warning about the missing data of the poisson's ratio.

Hi,

Please see if the following forum thread helps: Cam Clay (ansys.com)
