Identifying the dynamic compressive stiffness of a prospective biomimetic elastomer by an inverse method

► We identify the dynamic compressive response of a prospective soft-tissue-simulating elastomer using an inverse method. ► Finite element modeling combines with high-speed digital image correlation to identify the dynamic stiffness. ► The method eliminates measurement errors due to specimen inertia and friction effects. ► This elastomer's stiffness was unchanged over the six decades in strain rate examined.
