There are some materials in nature that experience deformations not elastic. Viscoelastic of them. We come across many such our daily lives through a number interesting applications engineering, material science and medicine. This article concerns itself with modelling the nonlinear response class viscoelastic solids. In particular, viscoelasticity strain rate type, which can be described by co...

Viscoelastic fluids are non-Newtonian that exhibit both "viscous" and "elastic" characteristics in virtue of mechanisms to store energy produce entropy. Usually the storage properties such modelled using same concepts as classical theory nonlinear solids. Recently new models for elastic solids have been successfully developed by appealing implicit constitutive relations, these offer a different...

handling of endodontic sealers is greatly dependent on their elasticity and flow ability. we compared the viscoelastic properties of three root canal sealers.ah plus (dentsply, de trey, konstanz, germany), endofill (dentsply hero, petrópolis, rio de janeiro, brazil) and ah26 (dentsply, de trey, konstanz, germany) were mixed according to the manufacturers' instructions. the resulted pastes were ...
