Numerical and experimental analysis of the damped energy of polymer material by viscoelastic behaivior

Mojtaba Soleimanipour, Hasan Khademizadeh

The intention of this paper is to give a comparative reviewofmaterial polymer such asRubber with special focus on impact analysis. For quasi-static problems,elastomers can be considered as incompressible ruber-like materials.In this research first in order to simulate the mentionedmaterial in impact condition,the coefficients related to viscoelastic equations and rubber constitutive equatoins, the properties of viscoelastic material as the terms of Prony series will be determined,then the hyperelastic model was obtained by using the results of an expriment .then by simulating rubber in the finite elemet code,(ABAQUS/Explicit) the expected analysis carried out. The result of simulating was compared with similar amount of practical,available result and by this the numerical method was conffirmed by experimental and theoritical results .at the end by simulating of impact expected out puts such as damped energy will be obtained.
