Parameters
----------
name
A String specifying the repository key.
region
A Region object specifying the region to which the predefined field is applied.
numBackStress
An Int specifying the number of backstresses. The default value is 1.
equivPlasticStrain
A sequence of Floats specifying the initial equivalent Plastic strain.
backStress
A sequence of sequences of Floats specifying the initial backstress tensor for kinematic
hardening models. The default value is an empty sequence.
sectPtNum
A sequence of Ints specifying section point numbers. This argument is valid only when
*definition*=SECTION_PTS.
definition
A SymbolicConstant specifying different types of kinematic hardening. Possible values
are KINEMATIC_HARDENING, CRUSHABLE_FOAM, REBAR, SECTION_PTS, and USER_DEFINED. The
default value is KINEMATIC_HARDENING.
rebarLayerNames
A sequence of Strings specifying rebar layer names. This argument is valid only when
*definition*=REBAR.
distributionType
A SymbolicConstant specifying whether the load is uniform. Possible values are MAGNITUDE
and ANALYTICAL_FIELD. The default value is MAGNITUDE.
Returns
-------
A KinematicHardening object.
