ResumoPublisher Summary The mechanical properties of polymers are controlled by the elastic parameters, the three moduli, and the Poisson ratio; these four parameters are theoretically interrelated. If two of them are known, the other two can be calculated. The moduli are also related to the different sound velocities. As the latter are again correlated with additive molar functions, the elastic part of the mechanical properties can be estimated or predicted by means of the additive group contribution technique. The mechanical properties of polymers are of interest in all applications where polymers are used as structural materials. Mechanical behavior involves the deformation of a material under the influence of applied forces. The simplest mechanical properties are those of homogeneous isotropic and purely elastic materials; their mechanical response can be defined by only two constants. For anisotropic, oriented-amorphous, crystalline, and oriented-crystalline materials, more constants are required to describe the mechanical behavior.
