Drucker-Prager model 1

[Biti Alessandra]

Hi Guys,
Regarding the Drucker-Prager model in Abaqus, I want to use it to model a granular/soil Material,

any Idea about inserting the cohesion value of the material in Abaqus model???

However, someone (who used Abaqus in his study) said in his article "the hardening was defined by the apparent cohesion".

 

[FEA way]

Check the documentation chapter "Extended Drucker-Prager Models". It provides the relation between cohesion and parameters of the Drucker-Prager model and even discusses the case when friction angle and cohesion values are available and the Drucker-Prager model has to be used instead of Mohr-Coulomb one (paragraph "Matching Mohr-Coulomb Parameters to the Drucker-pRager Model").
