- Abstract
- On example of cross-linked polymer received by curing of resorcinol diglicidic ester and metaphenylene diamine of composition 1:1 comparison of parameters of tension uniaxial deformation with constant rate expressed as a percentage and with constant load in wide diapason of rates and loads was conducted. It is revealed that physical and mechanical and other parameters of deformation can be calculated only after definition of deformation mechanism. It was supposed that methods with given load are most suitable for analysis of process kinetics. It was established that at given deformation rate sample always failures, but at given load sample failures leading off with specific load. Deformation with constant rate expressed in a percentage is occured with increased acceleration, but tension with constant load - with process inhibition. Relaxation of specimen conditioned by deformation of it is occured at small tension rates.
