number-cracks i

[read only] number of crack sets developed

strain-tension-plastic-1 f

[read only] accumulated plastic tensile strain in the direction $n_1$

strain-tension-plastic-2 f

[read only] accumulated plastic tensile strain in the direction $n_2$

strain-tension-plastic-3 f

[read only] accumulated plastic tensile strain in the direction $n_3$

Notes:

• Only one of the two options is required to define the elasticity: bulk modulus $K$ and shear modulus $G$, or Young’s modulus $E$ and Poisson’s ratio $\nu$. When choosing the latter, Young’s modulus $E$ must be assigned in advance of Poisson’s ratio $\nu$.
• The tension cut-off is ${\sigma}^t = min({\sigma}^t, c/\tan \phi)$.
