In the study of thermoelastic actuation of dielectric elastomer, we can write the Helmholtz free-energy as a function of stretch ratio, nominal electric displacement and temperature (T).

The entropy (S) is the negative partial differential coefficient of W with respect of temperature (T). And we can see the change of S is due to three components: deformation, heat conduction and polarization. In an isothermal state, the deformation part has been fully investigated by Arruda and Boyce in 1993, but the polarization-induced entropy (Sp) has not been clearly stated.

Hi All,

Most exisiting failure critera delevolped for fiber composite laminates and they are rough estimations for fabric composite. I want to know if there is a suitable failure criterion for fabric composites.

Thanks

Azadeh

Professor Herbert Hui, of Cornell University, has been named the 2011 recipient of The Adhesion Society Award for Excellence in Adhesion Science, Sponsored by 3M.

The Award will be presented during the 34th Annual Meeting of The Adhesion Society in Savannah, GA, USA, 13-16 February 2011.

I am preparing my PHD in the National Technical Univercity of Athens (Faculty of Applied Sciences ,Department of Mechanics). We have recently bought an instron fatigue model 1276 (static capacity 2000 kNt ,dynamic capacity 1000 KNt) from the Greek Army. The machine is in bad condition and it needs service. Unfortunately , the manuals of the machine are missing.The machine is quite old and it is very difficult to find the mannuals from the manufacturer . Does anybody has the manuals or knows where i can find them?
