Peculiarities of resilient highly elastic deformation of organic glasses with linear and rarely cross-linked structure

The peculiarities of resilient highly elastic behavior of organic glasses with linear and rarely crosslinked structure are investigated. The character of the development and decay of the highly elastic deformation in the range from room temperature to T r is obtained. It is established that glasses with various structure have no essential differences upon deforming in the range of deformations within ±0.8% and at temperatures from room temperature to the softening temperature T s . It is proposed to use an asymmetric multiparameter sigmoid function for the approximation of the equilibrium deformation surfaces.
