Peculiarities of Resilient Highly Elastic Deformation of Organic Glasses with Linear and Rarely Cross-linked Structure

摘要

The peculiarities of resilient highly elastic behavior of organic glasses with linear and rarely cross-linked 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.
