Journal ArticleDOI
On the application of bees algorithm to the problem of crack detection of beam-type structures
TL;DR: In this paper, the application of the bees algorithm (BA) to the problem of crack detection in beams is introduced, and a numerical as well as an experimental study is designed to predict a single open edge-crack in cantilever beams.
Journal ArticleDOI
Improvement of a vibration-based damage detection approach for health monitoring of bolted flange joints in pipelines:
TL;DR: In this paper, a vibration-based health monitoring strategy has been developed for detecting the loosening of bolts in a pipeline's bolted flange joint, which is a major concern in the oil and gas industry.
Journal ArticleDOI
Finite element model updating using bees algorithm
TL;DR: Comparison of the results indicates that BA is a simple and robust approach that could be effectively applied to the FE model updating problems.
Journal ArticleDOI
Application of a robust vibration-based non-destructive method for detection of fatigue cracks in structures
TL;DR: In this paper, an empirical mode decomposition (EMD) method was used to establish an effective energy-based damage index for detecting fatigue cracks in structures, which can be regarded as an efficient non-destructive tool, since it is simple, cost-effective and does not rely on analytical modeling of structures.
Journal ArticleDOI
A vibration-based strategy for health monitoring of offshore pipelines' girth-welds.
Pejman Razi,Farid Taheri +1 more
TL;DR: The results obtained from both the numerical and experimental studies confirm the integrity of the approach in identifying the existence, and progression of the advancing notch, and compare the performance of the two vibration excitation means in damage detection.
