# block contact material-table command

Syntax

block contact material-table keyword <range>

Primary keywords:

The material table is used to define the joint constitutive model and properties that should be assigned when new contacts form. By default, all new contacts are assigned the mohr material type. Use the commands below to change this default. No default properties are assigned. All large-strain models must supply default normal and shear stiffnesses at a minimum.

Entries can be added to the table to support the assignment of different joint constitutive models or properties for different ranges when new contacts form.

jmodel keyword

Add an entry to the material table that specifies the joint constitutive model to be used for new contacts that form and fall into the range.

bilinear-mohr
cyjm
elastic
mohr
power
softening-mohr
property keyword ...

Add an entry to the material table that specifies the joint property value to be used for new contacts that form and fall into the range.

apply

Apply the material table to set constitutive models of existing contacts according the the ranges

default keyword ...
jmodel keyword

Specify the default joint constitutive model to be assigned to new contacts. By default the mohr model is assigned to all new contacts.

bilinear-mohr
cyjm
elastic
mohr
power
softening-mohr
property keyword ...

Specify the default value $$f$$ for property keyword to be assigned to new contacts. There is no default, so generally a normal stiffness and shear stiffness must be specified.

list

Print out the material table (constitutive models, properties and ranges)

modify i keyword ...
jmodel keyword

Modify entry $$i$$ of the material table that specifies the joint constitutive model to be used for new contacts that form and fall into the range.

bilinear-mohr
cyjm
elastic
mohr
power
softening-mohr
property keyword ...

Modify the entry $$i$$ of the material table that specifies the joint property value to be used for new contacts that form and fall into the range.

remove <i > <all>

Remove entry $$i$$ from the material table.
