摘要

摘要:目前计算焊接接头疲劳强度的规范程序对低周载荷的应用有限，而且通常没有考虑工作应力循环不对称性的可能变化、预期残余应力水平的差异以及各种可能的接头几何形状。利用抗疲劳断裂的实验数据，以及疲劳失效各个阶段的物理模拟和应力-应变状态数值有限元研究的数据总结，开发了由高强度钢制成的外壳结构在内外压力载荷下的估计程序。

On the Fatigue Strength Calculation of Welded Shell Structures Made of High-Strength Steels under Low-Cycle Loading: Part 1. Estimation at the Initial Stage of Fatigue Failure

Abstract—Current regulatory procedures for calculation of the fatigue strength of welded joints are of limited use for low-cycle loads and, typically, do not consider a possible variation in the asymmetry of the operating stress cycle, differences in the expected level of residual stresses, and a variety of possible joint geometries. Estimation procedures for shell structures made of high-strength steels exposed to external and internal pressure loadings were developed using experimental data on the resistance to fatigue fracture, as well as by physical simulation of individual stages of fatigue failure and summarization of data from numerical finite element studies of the stress-strain state.

期刊介绍： Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
