Angle Degrees

The soil material is modeled using an ideally plastic Mohr-Coulomb material with weak dilatancy effects.

Soil Material Properties
Young's Modulus (MPa)30
Poisson's Ratio0.33
Density (Kgm-3)1500
Friction angle (°)30
Cohesion (kPa)0.05
Angle of dilatancy (°)5
Residual friction angle (°)30
Residual cohesion (kPa)0.05

The Mohr-Coulomb material can be defined using an evolving yield surface which shows hardening behavior, or simply perfectly plastic behavior. The cohesion and friction angle are defined as constant values listed in the table above for simplicity.
