Dynamic Mechanical Behaviour of Polymer Materials
Description
In this chapter, we present the current research program of dynamic mechanical behaviour of polymer materials. Polymers typically have low strength, stiffness and wave impedance, making it challenging to obtain accurate stress‐strain relations at high strain rates. The challenges in split Hopkinson bar testing technique modified for characterizing the mechanical response of polymers under high‐rate loading are introduced first. Then, various representative polymers are reviewed for illustrating the strain‐rate dependencies of mechanical data and their constitutive modellings.
