This monograph is an updated and extended edition of Strength and Fracture of Polymer Films, which was published in Russian in 1999. It presents the results of long-term theoretical and experimental studies of brittle and quasi-brittle fracture of solid polymers. The principal results of a comprehensive and detailed investigation of the statistical features of fracture of polymers and other solids under the conditions of separate and complex action various factors (temperature, mechanical stresses, surface-active media, UV irradiation, gamma-irradiation, chemical admixtures, thermal...
