Query: Hyperelastic constitutive modeling with exponential decay and
  application to a viscoelastic adhesive   Hyperelastic materials models are well established to describe the non-linear
stress-strain relations of elastomers. In this paper, a polyurethane adhesive
is considered as an exemplary material and subjected to tensile, compressive
and shear tests. Conventional hyperelastic models are unable to capture the
mechanical behaviour satisfyingly: If the model agrees with the test results at
large strains, it underestimates the stiffness at low strains significantly. We
propose a model extension to describe a kind of exponential decay of stiffness
which bears some similarity with a specific model developed by Yeoh. The new
hyperelastic model is coupled with linear viscoelasticity to account for the
strain rate dependence observed for the tested material. The model parameters
are identified using a tensile test at a single strain rate only and a creep
test. Furthermore, the compressibility is determined by comparison of the
stiffness in two butt joint tests with different aspect rations of the adhesive
layer. Using this parameter set the new model provides a very good prediction
of tensile, compressive and shear tests at different strain rates.
