Hello all,

I am doing my research on steel-laminated rubbers, as a result characterizing the rubber is a great amount of my work. While able to develop closed form solutions for the hyperelastic models ABAQUS is offering, things get more complicated when I want to include hysterisis in them.

So my question is: Is there any source where I could find closed form solutions including the hysteretic parameters (stress scaling factor etc.) or any source I could get more insight into that?

Thank you in advance

You can use the [URL= http://polyumod.com/download ]MCalibration[/URL] software to quickly explore different material models and parameters.

My [URL= http://polymermechanics.com/ ]Polymer Mechanics book[/URL] contains equations and source code examples.

Hi All,.

What is the simplest way to describe the physical significance of Neo-Hooekan parameters viz, C10 and D. Means, how does they affect the deformation etc.

C10 is half of the shear modulus, D is related to the bulk modulus and hence the compressibility of the material, i.e. for an incompressible material (poissons ratio =0.5) the deformation is controlled by the shear modulus only

C10 would be half the initial shear modulus

D would be two over the bulk modulus
