O A four-element model of springs and dashpots is better than a power-law equation in representing elastic, viscoelastic and viscous behaviour specifically. O Rubber elasticity theory doesn't work well at high tensile strains as the individual bonds become stretched. O Rubber elasticity theory predicts that the entropy of a rubber increases with both tensile and compressive loading. O An Isometric graph plotted from creep data can give a good representation of recovery. O Laminating a rubber block can increase the compressive stiffness as it increases the shear stress in each layer. O A four-element model of springs and dashpots is better than a power-law equation as it has fewer parameters that need finding
