Regarding ABAQUS

[Susmita Ghimire]

I am simulating soil-pile model in ABAQUS. For soil I need to input Drucker-prager failure criteria and the parameters given are:
E= 20Mpa
Soil unit wt. = m11.8Kn/m3
Poisson's ratio = 0.45
Cohesion = 34Kpa
friction angle = 16.5degree
dilation angle = 16.5 degree
shear wave velocity = (60-1200 m/s
coefficient of earth pressure at rest = 0.65
Here I am not sure where to input this cohesion as there is no any option for cohesion in Drucker-prager failure option.

 

[FEA way]

Check the documentation chapter "Extended Drucker-Prager models". Among the others, it describes relations with cohesion and there's even a chapter meant for users who have the data for Mohr-Coulomb model (including friction angle and cohesion) but would like to use the Drucker-Prager model instead.

Thank you very much. I checked it and saw that we can input cohesion in terms of shear as shear (cohesion) yield stress but my output is not correct.
