Detailed Description

template<typename TBaseClass = Element>
class itk::fem::Element2DMembrane< TBaseClass >

Class that is used to define a membrane energy problem in 2D space.

This class only defines the physics of the problem. Use his class together with element classes that specify the geometry to fully define the element.

A membrane element a two dimensional flat extensional element. There are two in plane displacement DOF's at each node of the element. The elements can be used to model two dimensional elasticity problems, plane strain and plane stress. The membrane element has no rotational stiffness or stiffness normal to the plane of the element. It can be situated arbitrarily in space but the resultant forces must lie in the plane of the element.

You can specify one template parameter:

TBaseClass - Class from which Element2DMembrane is derived. TBaseClass must be derived from the Element base class. This enables you to use this class at any level of element definition. If not specified, it defaults to the Element base class.
