Parameters
----------
table
A sequence of sequences of Floats specifying loading data. The first sequence must
contain only 0. At least two sequences must be specified if *type*=DAMAGE, and at least
3 sequences must be specified if *type*=ELASTIC_PLASTIC. The items in the table data are
described below.
temperatureDependency
A Boolean specifying whether the loading data depend on temperature. The default value
is OFF.
dependencies
An Int specifying the number of field variable dependencies included in the definition
of the loading data, in addition to temperature. The default value is 0.
tensileStiffnessFactor
A Float specifying the fraction of the initial compressive stiffness that defines the
stiffness in tension. The default value is 10–3.
type
A SymbolicConstant specifying a damage elasticity model or an elastic-Plastic model for
gasket thickness-direction behavior. Possible values are ELASTIC_PLASTIC and DAMAGE. The
default value is ELASTIC_PLASTIC.
unloadingDependencies
An Int specifying the number of field variable dependencies included in the definition
of the unloading data, in addition to temperature. The default value is 0.
unloadingTemperatureDependency
A Boolean specifying whether unloading data depends on temperature. The default value is
OFF.
variableUnits
A SymbolicConstant specifying the behavior in terms of units of force (or force in unit
length) versus closure or pressure versus closure. Possible values are STRESS and FORCE.
The default value is STRESS.
yieldOnset
A Float specifying the closure value at which the onset of yield occurs or the relative
drop in slope on the loading curve that defines the onset of Plastic deformation
(depending on the value of *yieldOnsetMethod*). The default value is 0.1.
yieldOnsetMethod
A SymbolicConstant specifying the method used to determine yield onset. Possible values
are RELATIVE_SLOPE_DROP and CLOSURE_VALUE. The default value is RELATIVE_SLOPE_DROP.
unloadingTable
A sequence of sequences of Floats specifying unloading data. The items in the table data
are described below. The default value is an empty sequence.
