Constitutive Law

This material is underdevelopment and only available in OSParticulas. More details will follow when done.

Material Properties

The isotropic variational mechanics model using a single energy release rate that scales evolution of damage. The critical energy release rate is enter using the base material JIc property. The other needed material properties are as follows:

Property Description Units Default
(Isotropic Properties) Enter all properties needed to define the underlying isotropic material response varies varies
ell Length scale parameter used in variational fracture mechanics none none
viscosity Viscosity to use when solving coupled phase field evolution in a diffusion tasks none none
gd Softening law with options 0 = quadratic, 1 = exponential, 2 = linear softening none 0
stability A stability factor thought to help post-failure analysis none 0
garg An optional argument for use within the softening law. If not provided, default values depend on gd and are 1, 3, and 4, for gd = 0, 1, or 2, respectively none varies
partition Choose the methods used to partition energy into energy that cause fracture and energy that does not cause fracture. The options are 0 = using eigenstrain analysis and 1 = divide into pressure and deviatoric strains none 1
(other) Properties common to all materials varies varies
