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 temperat...
