Further improvement of the Prometey model and Unified Curve method part 1. Improvement of the Prometey model

Autor: V. A. Shvetsova, V. I. Kostylev, V. N. Fomenko, A. G. Gulenko, Boris Margolin

Publikováno v: Engineering Fracture Mechanics. 182:467-486

The local approach to brittle fracture is able in principle to transfer fracture data from one type of specimens to another one for different test temperatures and different material conditions. However, in practice the capacity of existing models to

Methodology of Including Spatial Nonuniformity of Material Properties in the Brittle Fracture Resistance Calculation for WWER-1000 Reactor Pressure Vessels. Part 2. Experimental Investigations

Autor: A. A. Chernobaeva, V. N. Fomenko, A. A. Vakulenko, A. I. Minkin, Boris Margolin

Publikováno v: Strength of Materials. 47:515-523

Using experimental data the authors determine standard deviations of distribution of the ductile-tobrittle transition temperature TK for the base metal (in the vessel shell) and weld metal for WWER-1000 reactor pressure vessels. Based on the standard
