Detailed Description

This class defines a basic set of capabilities any elasticity tensor should have.

The ElasticityTensor (also called C_ijkl) is a 3x3x3x3 tensor that is represented here by a 9x9 matrix.

Note that there is a pure virtual function: calculateEntries. This function MUST be ovewritten by derived classes!

Constructor & Destructor Documentation

ElasticityTensor()

ElasticityTensor::ElasticityTensor

(

const bool

constant = false

)

Default constructor...

creates a 9x9 matrix.

Parameters

constant

Determines whether or not the matrix will get recomputed multiple times (false) or just once (true).

Member Function Documentation

calculate()

void ElasticityTensor::calculate

(

unsigned int

qp

)

Public function that will be called whenever the values for this matrix need to be filled in.

Definition at line 18 of file ElasticityTensor.C.

{
  if (!_constant || !_values_computed)
  {
    calculateEntries(qp);
    _values_computed = true;
  }
}

calculateDerivative()

ColumnMajorMatrix ElasticityTensor::calculateDerivative ( unsigned int  qp, unsigned int  i  )

virtual

Definition at line 28 of file ElasticityTensor.C.

{
  ColumnMajorMatrix m(9, 9);
  return m;
}

calculateEntries()

virtual void ElasticityTensor::calculateEntries ( unsigned int  qp )

protectedpure virtual

Pure virtual (must be overriden by derived class).

This method actually fills in the entries of the tensor... using whatever information it has.

Implemented in AnisotropicElasticityTensor, IsotropicElasticityTensor, and IsotropicElasticityTensorRZ.
