Analysis of the Effect of Shape Factor on Cork–Rubber Composites under Small Strain Compression

Like other types of elastomers, different geometries of the same cork–rubber material present different mechanical behaviour when subject to compression between bonded plates. To validate the application of Hooke’s Law on cork–rubber materials, under compression at small strains, a set of experiment...
