MAT_PIECEWISE_LINEAR_PLASTICITY Additional Properties (LS-DYNA)

Name	Defines the name of the modeling object.
Label	Specifies a unique numerical identifier for the modeling object.
Properties
Keyword option	LOG INTERPOLATION: Interprets the specified strain rate effect the specified LCSS table with logarithmic interpolation. STOCHASTIC: Allows for spatially varying yield and failure behavior.MIDFAIL: Checks failure by plastic strain at the mid-plane only.
Tangent modulus (ETAN)	Defines the tangent modulus of the material.
Failure flag (FAIL)	Controls how LS-DYNA handles failure.
Minimum time step for automatic element deletion (TDEL)	Defines the minimum time step size for automatic element deletion.
Strain rate parameter (C)Strain rate parameter (P)	Defines the value of the C parameter for strain rate for the Cowper and Symonds model.
Formulation for rate effects (VP)	Defines the formulation for viscoplastic rate effects.
Failure strain as a function of strain rate (LCF)	Lets you specify a DEFINE_CURVE modeling object that defines the XY function data for the strain rate. Select an existing curve from the list or click Create Modeling Object to create a new curve.For more information, see Defining XY data for LS-DYNA solutions.
