block zone cmodel command

Syntax

block zone cmodel keyword ... <range>

Primary keywords:

list    load    assign    imass

Assign a constitutive model to zones.

list keyword

List a summary of all dynamically loaded zone constitutive models, or, if the keyword used specifies a s, outputs information only for the model specified by s.

names <s >

List names and version numbers. (This is the default.)

properties <s >

List available properties.

states <s >

List possible states.

load s

Dynamically load a constitutive model. The dynamic library should have the name “modelname007.dll.” For example, model “mohr” would have a library name of “modelmohr007.dll.”

assign keyword

Assigns the dynamic constitutive model model to all of the zones in the range. If not already loaded, the system will attempt to automatically load the library.

The mechanical constitutive models are described in Constitutive Models, and the creep models are in Creep Constitutive Models.

anisotropic

transversely-anisotropic elastic model (see the Anisotropic model description).

burgers

classical viscoelastic model known as the Burgers substance which composed of a Kelvin model and a Maxwell model (only available for the creep option; see the Burgers model description).

burgers-mohr

viscoplastic model combining the Burgers model and the Mohr-Coulomb model (only available for the creep option; see the Burgers-Mohr model description).

double-yield

double-yield (cap) elasto-plasticity model (see the Double-Yield model description).

drucker-prager

Drucker-Prager elasto-plasticity model (see the Drucker-Prager model description).

elastic

isotropic elastic model (see the Elastic Model description).

hoek-brown

Hoek-Brown elasto-plasticity model (see the Hoek-Brown model description).

hoek-brown-pac

Hoek-Brown-PAC elasto-plasticity model (see the Hoek-Brow-PAC model description).

imass (option required)

Strain-softening model with two-mode sofetning of yield surfaces (see the IMASS model description).

maxwell

classical viscoelastic model known as the Maxwell substance, known also as Maxwell model (only available for the creep option; see the Maxwell model description).

modified-cam-clay

mohr-coulomb

Mohr-Coulomb elasto-plasticity model (see the Mohr-Coulomb model description).

mohr-coulomb-tension

Mohr-Coulomb elasto-plasticity model with tensile strain crack tracking, known also as the MohrT model (see the Mohr-Coulomb-Tension model description).

null

null model — for most purposes null models are ignored by default, and zones adjacent to them are treated as surfaces (see the Null model description).

orthotropic

orthotropic elastic model (see the Orthotropic model description).

power

two-component power law model used for mining applications (only available for the creep option; see the Power model description).

power-mohr

softening-ubiquitous

strain-softening/hardening elasto-plasticity model with bilinear failure and ubiquitous joints, known also as the SUBI model (see the Softening-Ubiquitous model description).

strain-softening

strain-softening/hardening elasto-plasticity model (see the Strain-Softening model description).

ubiquitous-joint

Mohr-Coulomb elasto-plasticity model with a plane of weakness, known also as UBI model (see the Ubiquitous-Joint model description).

ubiquitous-anisotropic

model with a plane of weakness and with anisotropic elasticity (see the Ubiquitous-Anisotropic model description).

wipp

a reference creep model commonly used in thermomechanical analyses associated with studies for the underground isolation of nuclear waste in salt (only available for the creep option; see the WIPP model description).

wipp-drucker
