Kinetic parameters, changeability deformation

Thus, we assumed that all three kinetic parameters of deformation in (20), Qo, a, and 0, are changeable, being the functions of temperature, strain, and stress. [Pg.178]

New possibilities for a comprehensive, precise analysis of the kinetics of polymer deformation under different experimental conditions, taking into account the changeability of kinetics under different temperature/deformation conditions. The LICRM setup made it possible not only to increase sharply the accuracy of the measurements, but also to study the deformation kinetics under formerly inaccessible conditions, namely (a) to obtain the complete kinetic information on polymer deformation in any temperature point and at any stage of the deformation process and (b) to determine activation parameters under conditions of practically unchangeable polymer structure and mobility.

Let us stress once more that, irrespective of the specific solid-state deformation model used [271-275,292], the values of creep activation parameters in polymers are interconnected and depend on the degree of deformation and temperature. Their changes are related in a regular manner to structural alterations in polymers and to their spectra of molecular motions. Due to the changeability of deformation kinetic... [Pg.185]
