Hi All,

I am a mechanical engineer with post-graduate qualification in materials engineering, and with 13 years of experience in the engineering design and simulation industry developing world class CAD / CAE software. I am currently on the lookout for challenging PhD positions in the materials mechanics domain where I can exercise the diversity of my skills and knowledge in a multidisciplinary environment.

Hi All,

I would like to know if anyone has had the opportunity to investigate cellular rubbers rheology. I am thinking of characterizing the viscoelastic properties of cellular rubber during cure and after cure in the rheometer, using ASTM D6601. What I am expecting is a distorted cellular structure due to very constrained foam expansion during the blowing agent's decomposition, so the results would obviously be different than the ones obtained from a DMTA machine.

Would like to hear from anyone with some rheology / viscoelastic characterization experience.
