Hi,

I am working in a SPH code, and I am a little stuck in handling elastic solids. I am following standard SPH as described in Gray, et al 2001. I am trying to validate my code simulating the collision of two rubber rings.

I am using the linear equation of state P = (co^2)*(rho - rhoRef). And I am wondering if the sound speed remains constant along the whole iteration process.

Any idea?

Thanks in advance,

Ruben
