ResumoThe macroscopic elastic behaviour of rubberlike solids is reviewed on the basis of the general theory of isotropic elasticity. Attention is restricted to homogeneous biaxial deformations since these provide stress–deformation data sufficient to characterize the strain-energy function of rubberlike solids. The incompressible theory is described first and then experimental data are discussed and represented in graphical forms yielding immediate theoretical interpretation. The main stress–deformation characteristics of rubberlike solids are thereby exposed. Specific forms of strain-energy function are also reviewed, the role of the Valanis–Landel hypothesis being highlighted. Macroscopic implications of molecular statistical theories are assessed briefly. The compressible theory is then developed and details of the theory of “nearly incompressible” elastic solids examined with a view to characterizing volume changes accompanying biaxial deformation. Experimental data are discussed in relation to the theory which is also viewed vis-à-vis structurally based theories.
