Only few works have been focused on soft materials at medium strain rates. In the present paper, we propose a new experimental setup to investigate the compressive response of rubber‐like materials in the range of intermediate strain rates, such experiments being difficult to conduct with conventional mechanical frames or traditional Hopkinson bar technique. The new apparatus consists in a hybrid...
Two different viscoelastic frameworks adapted to large strain rate-dependent response of elastomers are compared; for each approach, a simple model is derived. Within the Finite Linear Viscoelasticity theory, a time convolution integral model based on an extension to solid of the K-BKZ model is proposed. Considering the multiplicative split of the deformation gradient into elastic and inelastic parts,...
