Chapter 11 PREDICTION, STABILIZATION, AND MODIFICATION OF SERVICE PROPERTIES OF POLYMERS FROM DISCRETE STRENGTH SPECTRUM AND RELAXATION SPECTROMETRY
As follows from Chapters 4, 7, and 8, the concepts of classical kinetic lifetime Zhurkov theory are applicable and convenient for the prediction of lifetime and its limiting characteristics for the bulk samples when the mean values of lifetime in the corresponding statistical curves coincide with the most probable values. However, under the complex testing conditions (including the case of thin films and fibers), the Zhurkov lifetime isotherms look quite unusual (break points, discontinuities, bends, etc.). This fact complicates the assessment and prediction of lifetime characteristics as well as the investigation of the specific features of fracture. As was shown above (Chapters 4, 7, and 8), the above classical concepts do not correlate with the results of the statistical kinetics of fracture. This important problem of the prediction of strength properties was described in many works [4, 18, 42, 45, 48, 56, 71, 77, 108, 114, 252, 302-308, 319, 324, 391, 393, 446, 447, 553-578]. The approach advanced in this monograph is based on the analysis of the distribution curves and is free from the above drawbacks because, under any conditions, the statistical curves preserve their topology.
