Numerous material models are available in NairnMPM. For those working with source code, you can create your own material types.

Define a Material

You create materials using a Material command block. Within that block all material properties are set using property commands. Refer to each material type to learn about its possible properties.

Linear Elastic Small Strain Materials

The materials in this section are all small-strain, linear elastic materials. They account for rotations by using a hypoelastic correction (using an approximate polar decomposition of the incremental deformation and done to second order in 2D and first order in 3D).

Name	ID	Description	Pσ	Pε	AS	3D
Isotropic	1	Linear elastic, isotropic	X	X	X	X
Transverse	2	Linear elastic, transversely isotropic with unique axis in the z direction	X	X	X	X
Orthotropic	4	Linear elastic, orthotopic material	X	X	X	X
Bistable	10	Elastic, isotropic material with two stable states having different properties	X	X	X

The table columns on the right indicate if each material can be used in plane stress (Pσ), plane strain (Pε), axisymmetric (AS), or 3D calculations.

Hyperelastic Materials

The materials in this section are designed to solve finite strain (or large deformation) problems. They are formulated using hyperelasticity methods.

The table columns on the right indicate if each material can be used in plane stress (Pσ), plane strain (Pε), axisymmetric (AS), with a 3D membrane (3M), or 3D calculations.

Elastic-Plastic Small Strain Materials

The materials in this section are all small-strain, elastic-plastic materials. They account for rotations by using a hypoelastic correction analagous to Jaumann Derivative methods. They handle plasticity by combining one of these materials with any compatible hardening law.

Hyperelastic-Plastic Materials

The materials in this section are formulated within the framework of hyper elasticity formulation. They can handle plasticity by combining them with any compatible hardening law.

Name	ID	Description	Pε	AS	3D
HEIsotropic	24	Isotropic, hyperelastic-plastic material	X	X	X
HEMGEOSMaterial	25	Isotropic, hyperelastic-plastic material using a Mie-Grüneisen equation of state.	X	X	X
ClampedNeohookean	29	Isotropic, hyperelastic-plastic material with tensile and compression elongations clamped to critical values.	X	X	X

The table columns on the right indicate if each material can be used in plane stress (Pσ), plane strain (Pε), axisymmetric (AS), or 3D calculations.

Softening Materials

The materials in this section will model material softening to emulate damage and fractures.

Name	ID	Description	Pσ	Pε	AS	3D
IsoSoftening	50	Small-strain isotropic material with damage and softening	X	X	X	X
IsoPlasticSoftening	53	Small-strain isotropic material that combines plasticity with damage and softening	X	X	X	X
TransIsoSoftening	51	Small-strain transversely isotropic material with damage and softening and with unrotated axial direction in the z (or θ is axisymmetric) direction		X	X	X
OrthoSoftening	54	Small-strain orthotropic material with damage and softening		X	X	X
OrthoPlasticSoftening	56	Small-strain orthotropic material with damage, plasticity, and softening		X	X	X
IsoPhaseFieldSoftening	57	Isotropic phase field material for variational fracture mechanics	X	X	X	X
IsoDamageMechanics	58	Isotropic material that damage by isotropic or scalar damage mechanics	X	X	X	X

The table columns on the right indicate if each material can be used in plane stress (Pσ), plane strain (Pε), axisymmetric (AS), or 3D calculations. Softening materials model failure by particle undergoing decohesion. The particle remain in the simulations and will continue to open their implied cracks. Alternativelym failure particles can be removed with the DeleteDamaged Custom Task.

Viscoelastic Materials

The materials in this section are viscoelastic materials.

Name	ID	Description	Pσ	Pε	AS	3D
Viscoelastic	7	Small-strain, linear viscoelastic material with sum of relaxation times	X	X	X	X

The table columns on the right indicate if each material can be used in plane stress (Pσ), plane strain (Pε), axisymmetric (AS), or 3D calculations.

Phase Transition Materials

The materials in this section control phase transitions between two other materials.

Name	ID	Description	Pσ	Pε	AS	3D
PhaseTransition	30	A first order phase transition between two materials		X	X	X

The table columns on the right indicate if each material can be used in plane stress (Pσ), plane strain (Pε), axisymmetric (AS), or 3D calculations.

Membrane Materials

The materials in this section will model membranes using lines of particles in 2D or planes of particles in 3D. Membranes are in development and only available in OSParticulas. They have been useful in some simulations. They are based in deformation within the membrane and likely do not model bending stiffness well. Further development is needed.

Name	ID	Description	2M	3M
MooneyMembrane	40	Membrane material based on a Mooney-Rivlin material	X	X

The table columns on the right indicate if each material can be used for a membrane in 2D calculations (2M) or in 3D calculations (3M).

Rigid Materials

Rigid materials can be used either to apply moving velocity, temperature, or concentration boundary conditions or to interact with non-rigid material by contact mechanics.

Name	ID	Description	Pσ	Pε	AS	3D
RigidBC	11	A rigid material that sets moving boundary conditions on the grid	X	X	X	X
RigidContact	35	A rigid material that that interacts with other materials by contact	X	X	X	X

The table columns on the right indicate if each material can be used in plane stress (Pσ), plane strain (Pε), axisymmetric (AS), or 3D calculations.

Material Class Hierarchy

Materials are C++ classes. The following class hierarchy shows the orginzation of those C++ classes in the NairnMPM source code. A material in green is an abstract class that is never assigned to particles. All others are material classes (by their name or their ID in parentheses). For those creating their own materials, they must be inserted in this hierarchy using a unique name and ID:

-Numerous material models are available in NairnMPM and '''OSUParticulas'''.
+Numerous material models are available in [[NairnMPM]]. For those working with source code, you can [[Creating MPM Materials|create your own material types]].
 == Define a Material ==
-=== Scripted Input Commands ===
+You create materials using a [[Material Command Block|<tt>Material</tt> command block]]. Within that block all material properties are set using property commands. Refer to each material type to learn about its possible properties.
-To use a material in calculations, you first must define it in the input commands. This definition will create a material ID (any string or number) that can be used to assign that material to particles. When using [[NairnFEAMPM]] or [[NairnFEAMPMViz]], a material is created with the command block:
- Material ID,name,type
-    Property value
-    Property2 value
-       .
-       .
- Done
-where
-* <code>ID</code> is the material ID (any string or number) that is used to reference this material in other commands.
-* <code>name</code> is a name that will appear in output files to describe the material
-* <code>type</code> is the type of material, which can be set by using material type name or material type ID from the available [[#toc|material models]] (see material tables on this page for each material's name and ID)
-Each material property is specified on a line with a property name and its value. Refer to each [[#toc|material type]] to see the available properties and which ones are required properties. The property names are case sensitive (although [[NairnFEAMPM]] can usually handle any case).
-=== XML Input Commands ===
-A material definition in a <code>XML</code> input file has the form:
- &lt;Material Type='1' Name='Polymer'&gt;
-    &lt;Property&gt;value&lt;/Property&gt;
-    &lt;Property2&gt;value&lt;/Property2&gt;
-       .
-       .
- &lt;/Material&gt;
-where
-* <code>Type</code> is the material type and must be entered by material type ID corresponding to that [[#toc|material models]] (see material tables on this page for each material's ID).
-* <code>Name</code> is any user-defined description of the material.
-Each material property is specified in a single <code>XML</code> element matching the property name and the content of the element as the value. Refer to each [[#toc|material type]] to see the available properties and which ones are required properties.
-Note that in <code>XML</code> files a material does not have an ID that is used in scripting files to refer to that material in other commands. Instead, other <code>XML</code> commands refer to defined materials by number or name as follows:
-; By Numbers
-: In this method, you use <code>mat='#'</code> attributes to refer to materials where # is the material number. The materials are defined by numbers in the order they appear in the output file with the first material being number 1. You have to be careful to use the correct number. If you add new materials to a file, it is best to add them to the end of the materials list, otherwise previous commands that referenced materials after an inserted material, will point to the wrong material.
-;By Name
-: In this method, you use <code>matname='Mat_Name'</code> attributes where <code>'Mat_Name'</code> matches the <code>Name</code> attribute of any defined material in the file. You can use these names even before the materials are defined, but an error will occur if you reference materials that are never defined. When referring to materials by name, you must be certain that all material <code>Name</code> attributes have unique strings.
-When referring to materials by name, the defined materials will appear in the output file in the ordered referenced rather than in the order defined in the input file. For this reason, you should not refer to some materials by name and others by number in the same file. The eventual ordering will likely mean the numbers will refer to the wrong material. The naming method is preferred in hand-edited <code>XML</code> files. If you use both <code>mat</code> and <code>matname</code> attributes in a single element, the <code>matname</code> attribute will be used and the <code>mat</code> will be ignored.
