Abstract: To evaluate if the multistable behaviour of corrugated plastic sheets under low tensile strain is a purely elastic phenomenon, tensile strain experiments were performed on thin silicone rubber sheets with corrugations. To perform such experiments, thin silicone rubber sheets with and without corrugations were cast by using a voltage controlled spin-coater. For the characterization of the sheets, a micrometer was used to measure the thickness in order to obtain values for the average thickness and homogeneity of the sheets. A protocol for tensilse tests on smooth thin silicone rubber sheets by using an Instron tensile test machine was formulated to obtain a value for the Young’s Modulus of the used silicone rubber experimentally. A series of low tensile strain experiments was carried out on a set of thin silicone rubber sheets with different kinds of corrugation patterns, after which the behaviour of these sheets was compared to the behaviour of corrugated plastic sheets under the same tensile strain.
