EPS foam library for NX 7.5

[ce.martos]

Dear:
I would like to obtain the αi βi µi constants for EPS (10, 12, 16, 24 and 32 kg/m3 density) in order to make a EPS material library in siemens NX 7.5 for the densities mentioned below.

The software requied that constant in its material library for foams materials.



Is are there any experimental data available of this constants to introduce to software´s library ?

I will apreciate your help and support.

Best regards.

Carlos Martos.

I don't have the experimental data. Do you have material samples that can be used for experimental testing?

Dr Bergstrom:

Thank's a lot for reply Me. Is possible that I obtain a material samples that can be used for experimental testing, I need the αi, βi, µi for the hyperfoam model in order to use in material library for Siemens NX 7.5. I am working in Mexico in a proyect that need to model a Insulated Foam Concrete house construction system using EPS with NX and need thats constants to make a non lineal simulation using FEA.

Is possible that you support Me, in how can I obrain that constant, what is the dimentions of the material samples, what test are required, what matematical model or software is required to obtain the constant using stress - strain that, etc?

Than´s for your time and support.

Saludos...
