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!

ElasticityTensor::ElasticityTensor ( const bool  constant = false)

Default constructor...

creates a 9x9 matrix.

Parameters

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.
