Mooney-Rivlin Material Definition dialog box

Property View
Select the Mooney-Rivlin material type you want to define. You can select the Samcef Mooney Rivlin type, the Abaqus Mooney Rivlin type, the ANSYS Mooney Rivlin type, or the Simcenter Nastran Mooney Rivlin MATHE type.
Properties
Mass Density (RHO)	Lets you define the material mass density.

Samcef Mooney Rivlin material

The following pages appear when you select Samcef Mooney Rivlin from the Property View list.
Mechanical page
Bulk Modulus (K)	Lets you define the compressibility coefficient.This coefficient can be constant or defined with a temperature dependent field.For more information, see the BULK parameter of the Samcef Mooney-Rivlin material.
Distortional Deformation page
Number of Points (NTPS)	Lets you define the number of Samcef Cicoefficients you want to use for the Samcef Mooney-Rivlin law's equation.See the note below about the Distortional Deformation - (Aij) table.
Table of coefficients	Define the Ci coefficients of the equation.All the coefficients can be constants or defined with a temperature dependent field.
Thermal page
Temperature (TREF)	Lets you define the material Reference Temperature.For more information, see the TREF parameter of the Samcef Mooney-Rivlin material.
Thermal Expansion Coefficient (TEXP)	Lets you define the material's CTE.The CTE can be constant or defined with a temperature dependent field.For more information, see the A parameter of the Samcef Mooney-Rivlin material.

Note:

In the Distortional Deformation - (Aij) table, the Samcef Ci coefficients of the law are defined as:

Row	Column 1	Column2	Column3	Column4	Column5
1		C2	C5	C9	C14
2	C1	C4	C8	C13
3	C3	C7	C12
4	C6	C11
5	C10

Linear part of the law

Coefficients: C1, C2

Parabolic part of the law

Coefficients: C3, C4, C5

Cubic part of the law

Coefficients: C6, C7, C8, C9

4th order part of the law

Coefficients: C10, C11, C12, C13, C14

For more information, see the Samcef Mooney-Rivlin material page.
