Abstract
The effect of the internal pressure of the gas in a pore or a cracklike defect on the critical fracture stress has been studied using fracture mechanics approaches. An analytical expression was derived for the dependence of the critical fracture stress on the internal pressure in the crack. The results of this work can be used in powder metallurgy and additive manufacturing of novel materials.
期刊介绍：
Doklady Physical Chemistry is a monthly journal containing English translations of current Russian research in physical chemistry from the Physical Chemistry sections of the Doklady Akademii Nauk (Proceedings of the Russian Academy of Sciences). The journal publishes the most significant new research in physical chemistry being done in Russia, thus ensuring its scientific priority. Doklady Physical Chemistry presents short preliminary accounts of the application of the state-of-the-art physical chemistry ideas and methods to the study of organic and inorganic compounds and macromolecules; polymeric, inorganic and composite materials as well as corresponding processes. The journal is intended for scientists in all fields of chemistry and in interdisciplinary sciences.
