The Yeoh material model is described in terms of the strain energy potential, W, 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 Yeoh 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 Yeoh material model on the Hyperelastic Material Definition dialog box.
