.DruckerPragerHardening

Required arguments

table

A sequence of sequences of Floats specifying the items described below.

Optional arguments

type

A SymbolicConstant specifying the type of data defining the hardening behavior. Possible values are COMPRESSION, TENSION, and SHEAR. The default value is COMPRESSION.

rate

A Boolean specifying whether the data depend on rate. The default value is OFF.

temperatureDependency

A Boolean specifying whether the data depend on temperature. The default value is OFF.

dependencies

An Int specifying the number of field variable dependencies. The default value is 0.

Table data

  • Yield stress.

  • Absolute value of the corresponding plastic strain. (The first tabular value entered must always be zero.)

  • Equivalent plastic strain rate, ε¯˙p⁢l, for which this hardening curve applies.

  • Temperature, if the data depend on temperature.

  • Value of the first field variable, if the data depend on field variables.

  • Value of the second field variable.

  • Etc.

Return value

A DruckerPragerHardening object.

Exceptions

RangeError.

setValues(...)

This method modifies the DruckerPragerHardening object.

Required arguments

None.

Optional arguments

The optional arguments to setValues are the same as the arguments to the DruckerPragerHardening method.

Return value

None.

Exceptions

RangeError.

Members

The DruckerPragerHardening object has members with the same names and descriptions as the arguments to the DruckerPragerHardening method.
