ALPHAThe classic Drucker-Prager model [10] is applicable to granular (frictional) material such as soils, rock, and concrete and uses the outer cone approximation to the Mohr-Coulomb law. The input consists of only three constants:Cohesion value (> 0)Angle of internal frictionDilatancy angleThe amount of dilatancy (the increase in material volume due to yielding) can be controlled via the dilatancy angle. If the dilatancy angle is equal to the friction angle, the flow rule is associative. If the dilatancy angle is zero (or less than the friction angle), there is no (or less of an) increase in material volume when yielding and the flow rule is non-associated.The dilatancy angle (the input dilatancy constant). When dilatancy angle = friction angle, the flow rule is associated and plastic straining occurs normal to the yield surface and there will be a volumetric expansion of the material with plastic strains. If dilatancy angle is less than friction angle there will be less volumetric expansion and if dilatancy angle is zero, there will be no volumetric expansion.
