Analysis on dynamic mechanical behavior for optical adhesive based on Abaqus

The effect of dynamic mechanical behavior of adhesives on the dropping reliability of device is very important. The dynamic mechanical parameters of optical adhesive are defined on the basis of the constitutive models of hyperelasticity and viscoelasticity in Abaqus, the static compression and dynamic ball dropping test are simulated and analyzed by Abaqus/Explicit, and the simulation results are verified by the comparison with the test results. The results illustrated that, the dynamic mechanical behavior of optical adhesive in the range from quasi static to high strain rate can be effectively defined and presented using the constitution models of hyperelasticity and viscoelasticity.
