Abstract

Structural integrity and life assessment of railway and aeronautical components, critical for the safety of these two important means of transport, is analysed using four case studies, two for each of them. In respect to railway components, a brief failure analysis of a fractured wheel is presented, with the idea to use this experience to improve structural integrity of wheels in general. Second case study is focused on coupling link used in freight wagons, once again providing failure analysis to improve its safety. Case studies of aeronautical components comprise torque links and High Temperature and Pressure (HTP) casings, as crucial components of airplane landing gear and jet engine, respectively. In both cases residual fatigue life was in focus with an aim to replace damaged torque link with a new one, produced by Additive Manufacturing (AM), and to check if damaged HTP casing can remain in operation for a certain period o time.

铁路和航空部件的结构完整性和寿命评估。四个案例研究的回顾

铁路和航空部件的结构完整性和寿命评估对这两种重要交通工具的安全至关重要，本文使用四个案例研究进行了分析，每个案例研究两个。就铁路部件而言，本文介绍了一个断裂车轮的简要失效分析，目的是利用这一经验来提高车轮的整体结构完整性。第二个案例研究的重点是用于货车的联轴节，再次提供故障分析，以提高其安全性。航空部件的案例研究包括扭矩链接和高温高压（HTP）套管，分别是飞机起落架和喷气发动机的关键部件。在这两种情况下，剩余疲劳寿命都是重点关注的，目的是用增材制造（AM）生产的新扭矩连杆替换损坏的扭矩连杆，并检查损坏的HTP套管是否可以在一定时间内保持运行。

期刊介绍： Theoretical and Applied Fracture Mechanics'' aims & scopes have been re-designed to cover both the theoretical, applied, and numerical aspects associated with those cracking related phenomena taking place, at a micro-, meso-, and macroscopic level, in materials/components/structures of any kind. The journal aims to cover the cracking/mechanical behaviour of materials/components/structures in those situations involving both time-independent and time-dependent system of external forces/moments (such as, for instance, quasi-static, impulsive, impact, blasting, creep, contact, and fatigue loading). Since, under the above circumstances, the mechanical behaviour of cracked materials/components/structures is also affected by the environmental conditions, the journal would consider also those theoretical/experimental research works investigating the effect of external variables such as, for instance, the effect of corrosive environments as well as of high/low-temperature.
