| Abstract: |
In this study, we have presented a wide variety of temperature experiments of a commercially available VHB polymer ranging from -30◦C to 80◦C at various strain rates and stretch levels under homogeneous deformation and temperature fields. The study demonstrates a pronounced influence of the temperature field on mechanical responses of the VHB polymer. After a wide range of experiments, we have proposed a finite-strain thermo-viscoelastic constitutive model where a non-linear evolution law is devised based on the classical concept of multiplicative decomposition of the deformation gradient. Then, decoupled one-dimensional equations are fitted to identify relevant material parameters appearing in the model. The thermo-viscoelastic model validation shows its excellent capability to predict the experimental results. |
