Simulation in Materials
DISROC allows modeling coupled Therom-Hydro-Mechanical processes fractured porous media.
In the standard version of DISROC:
and the coupling between these phenomena is introduced by the thermal expansion and the Biot coefficients (thermo-poroelasticity).
In the advanced version of Disroc, coupling effects from mechanics to hydraulic and from thermal to hydraulic (thermal pressurization)
can also be modeled as user defined couplings.
Disroc has a rich catalog of no linear constitutive models for bulk materials, interfaces and reinforcements.
Constitutive models available in Disroc include anisotropic elasticity, plasticity with hardening
(isotropic, kinematic) as well as viscoplasticity and damage.
Interface models in Disroc cover advanced cohesive zone models allowing the simulation of mixed modes fracture propagation.
Thermo-Hydro-Mechanichal coupled phenomena around petroleum boreholes, deep underground oil and gas storage caverns and shafts, deep nuclear waste
disposal etc. have been modeled by DISROC.
- Thermal diffusion is modeled according to the Fourier's law of head conduction,
- Hydraulic diffusion in modeled according to the Darcy's law for porous bulk material and by the Poiseuil's law (cubic lubrication law)
- Mechanical deformation in modeled with advanced elastic-plastic and viscoplastic models for geomaterials (see the catalog of materials)
