Temperature is well known to have a significant effect on the overall mechanical performance of viscoelas-

tomers. In this work, we investigate the thermo-mechanically coupled behavior of VHB 4910 using a combined

experimental and modeling approach. We first characterize the material behavior by performing a set of large

deformation uniaxial experiments at different temperatures. We then model the observed thermo-mechanical

behavior and calibrate that model to the uniaxial experiments. Lastly, the model is implemented as a user

material subroutine in a finite element package for validation purposes. A key finding of this work is that while

increasing the temperature stiffens the elastic contribution, it concurrently reduces the viscoelastic contribution

to the overall behavior of VHB.
