Detailed Description

Abstract base class for all material models.

Declares the basic common interface to all material models. Derived classes should expand this interface, because they are assumed to be base classes for analysis specific tasks (for example mechanical or thermal analysis).

Instance of integration point class is assumed to be implicit argument to all method, depending on internal state in point of consideration. To provide opportunity for storing arbitrary material model related history variables in integration points, associated material status class is introduced. Each new material model class should be declared together with its associated status class (derived from MaterialStatus class). This status can be seen as simple container, storing necessary history variables and providing some access and modification methods. Each integration point can contain material status. Material model should create unique copy of its associated status in each integration point. Because integration point is parameter of all messages to material model class, material model therefore can easily access all history variables it needs.

The attribute 'propertyDictionary' contains all the properties of a material like its Young modulus, its mass density or Poisson ratio.

Its task is to indicate whether there required material mode is valid for receiver (method hasMaterialModeCapability). Note: for some material models and linear materials there need not exist support for assembling material char matrix at material level, all is handled properly at crossSection level (_2dBeam mode, 3dShellMode, ...). But this function must indicate whether mode is valid or not for real stress computation.

virtual int oofem::Material::packUnknowns	(	DataStream &	buff,
		TimeStep *	tStep,
		GaussPoint *	ip
	)

inlinevirtual

Pack all necessary data of integration point (according to element parallel_mode) into given communication buffer.

The nature of packed data is material model dependent. Typically, for material of "local" response (response depends only on integration point local state) no data are exchanged. For "nonlocal" constitutive models the send/receive of local values which undergo averaging is performed between local and corresponding remote elements.

Parameters

buff	Communication buffer.
tStep	Solution step.
ip	Integration point.

double oofem::Material::castingTime

protected

Casting time.

For solution time less than casting time the material is assumed to have no stiffness etc. This attribute is declared here, but support for this functionality must be incorporated by particular material model

Definition at line 113 of file material.h.

Dictionary oofem::Material::propertyDictionary

protected

Property dictionary.

Can be used to store constant material parameters, which are same for all integration points. Note: Try to avoid using the dictionary because of a very slow access. Use rather separate variables to store material parameters.
