1. Failure Analysis. Overview. Analyzing failures is a critical process in determining the physi- cal root causes of problems. The process is complex, draws upon. Properly performed, failure analysis and RCA are critical steps in the overall problem-solving The importance and value of failure analysis to safety, reliability. Failure analysis is an engineering approach to determining how and why (cause and root cause) an equipment or a component has failed.

Due to migration of article submission systems, please check the status of your submitted manuscript in the relevant system below:. Once production of your article has started, you can track the status of your article via Track Your Accepted Article. Engineering Failure Analysis publishes research papers describing the analysis of engineering failures and related studies.

Papers relating to the structure, properties and behaviour of engineering materials are encouraged, particularly those which also involve the detailed application of materials parameters Papers relating to the structure, properties and behaviour of engineering materials are encouraged, particularly those which also involve the detailed application of materials parameters to problems in engineering structures, components and design.

In addition to the area of materials engineering , the interacting fields of mechanical, manufacturing, aeronautical, civil, chemical, corrosion and design engineering are considered relevant.

Activity should be directed at analysing engineering failures and carrying out research to help reduce the incidences of failures and to extend the operating horizons of engineering materials.

Emphasis is placed on the mechanical properties of materials and their behaviour when influenced by structure, process and environment. Metallic, polymeric, ceramic and natural materials are all included and the application of these materials to real engineering situations should be emphasised.

The use of a case-study based approach is also encouraged. Engineering Failure Analysis provides essential reference material and critical feedback into the design process thereby contributing to the prevention of engineering failures in the future.

All submissions will be subject to peer review from leading experts in the field. Authors submitting their research article to this journal are encouraged to deposit research data in a relevant data repository and cite and link to this dataset in their article. If this is not possible, authors are encouraged to make a statement explaining why research data cannot be shared. There are several ways you can share your data when you publish with Elsevier, which help you get credit for your work and make your data accessible and discoverable for your peers.

Fractography in failure analysis

This work describes one of the recent activities in progress at the LANAF, in which fatigue crack initiation and propagation lives have been estimated for an idealized aeronautical part tested in the laboratory, under variable amplitude loading condition — VAL, i.

A semi-automated procedure to estimate fatigue lives under VAL has been developed and implemented by which a virtual marking load pattern is generated and compared to the real pattern determined fractographically.

All rights reserved. Keywords: Aluminium alloys; Fatigue markings; Fractography; Marker loads; Quantitative fractography 1. Introduction Fractographic techniques using scanning electron microscopes SEM are extensively used in failure analysis of aeronautical components and structures [1—5].

The more advanced procedure employed on the fatigue life estimation of in-service or in-test fractured components undergoing variable amplitude loading — VAL, is depicted in Fig.

The technique consists basically of generating a virtual pattern of fatigue load marks provided by the applied loading spectrum, using preferably computational techniques, and compares it with the pattern actually recorded on the fracture surface of the component, obtained through microscopic survey.

In order to estimate fatigue lives spent in both crack initiation and propagation stages, it is necessary to obtain a plot similar to Fig.

The correct determination of fatigue crack initiation and propagation lives has obvious and important implications for several steps of aircraft fabrication and maintenance, such as materials selection, compo- nent design, manufacturing processes, non-destructive inspection programs, and the ultimate failure analysis as well. In this work, an idealized aeronautical component was fatigue tested in a laboratory environment in order to simulate its in-service performance under VAL.

After testing, the fracture surfaces were thoroughly analyzed in a SEM. The methodology described in Fig. Materials and component tested A 1. The microstructure of the aluminium alloy is showed in Fig. Texture is found in the rolling direction, L. Wide non-recrystallized regions and segregation can be observed in LS, and particularly, in TS planes. Experimental and analytical An idealized aeronautical component designed by LANAF was fatigue tested under a VAL spectrum expected to occur in the lower wing skin panels of commercial aircraft.

Consequently, a compression loading is generated in the opposite face of the tested part. Fatigue crack growth data as determined by quantitative fractography [2]. ND: non-detected.
