A new approach for evaluation of risk priorities of failure modes in FMEA [PDF]

open access: yes, 2001
This paper presents a method for carrying out the calculus of the risk priority of failures in Failure Mode and Effect Analysis (FMEA). The novelty of the method consists of new management of data provided by the design team, normally given on ...

Quantitative Limit State Assessment of a 3-Inch Carbon Steel Pipe Tee in a Nuclear Power Plant Using a Damage Index

open access: yesEnergies, 2020
Seismic motions are likely to cause large displacements in nuclear power plants because the main mode of their piping systems is dominated by the low-frequency region.

Study on Residual Strength of Composite Crescent Worn Casing

open access: yesShiyou jixie, 2022
Previous studies on the casing residual strength mainly focus on unworn casings or single crescent worn casings,but the influence of composite crescent worn shape on the casing residual strength was not fully studied.Therefore,the laboratory tests of ...

Effect of Adhesive Type and Overlap Length on the Mechanical Resistance of a Simple Overlap Adhesive Joint

open access: yesU.Porto Journal of Engineering, 2021
The present study focuses on the experimental determination of the mechanical behaviour of simple lap joints subjected to quasi-static tensile loads. Four different specimens were tested, resulting from the combination of two different adhesives (ductile
