From the experimental results it is impossible to decouple the fluid contribu?on from the solid contribu?on to the force?me response of the composite. In this work, we have developed a simple model of the fluid-flow dynamics that it is able to predict the fluid contribu?on in the energy dissipa?on of the Rheinforce cork composites under impact loads. To that end, we model the viscous flow inside a microchannel for a known displacement of the upper lid h(t, x), calcula?ng as a result the needed force to create that movement. eng open access Flujos (Sistemas dinámicos diferenciales) Modelling the squeeze flow in a deformed rectangular microchannel. conference output
