Reduced Polynomial Form of Order 2
The equation of strain energy potential, W in Reduced Polynomial form of order 2 is as follows:
where , , , are material constants.
You can use materials constants to calculate the initial shear modulus as follows:
You can also calculate initial bulk modulus for the material as follows:
When you select Reduced Polynomial form of order 2 material model to define the hyperelastic material, you must specify values for , , , .
For materials that are nearly incompressible, Creo Simulate uses incompressibility conditions. If the specified values of and is less than,
Creo Simulate uses following values of and during the analysis:
=.
=
where G is the initial shear modulus.
Creo Simulate calculates these constants when you select Reduced Polynomial form of order 2 material model on the Hyperelastic Material Definition dialog box.
