This research paper presents a novel structural health monitoring strategy based on hybrid machine learning and finite element model updating method for the of bolted connections in steel planer frame structures using vibration data. Towards this, support vector is trained with discriminative features obtained from time history data, those are used to distinguish between damaged undamaged joint...

The aerospace, automotive and marine industries have witnessed a rapid increase of using adhesive bonded joints due to their advantages in joining dissimilar and/or new engineering materials. Joint strength is the key property evaluating capability joint. In this paper, developments black-box grey-box machine learning (ML) models are presented allow accurate predictions failure load single lap ...

The rapidly increasing use of structural adhesives, especially in the joining automotive body structures has motivated various investigations effects adhesive curing process on joints. automotive-grade adhesives require heat curing, which, meantime, performs thermal loading substrates and causes undesirable joint. For example, results complex residual stresses bond which are detrimental to perf...

In order to achieve a high-quality joining of aluminum (Al) and copper (Cu) dissimilar metals, new friction stir double-riveting welding (FSDRW) with Cu rod as the rivet was proposed, rotating tool large concave angle shoulder specially designed. The results showed that under thermal–mechanical effect tool, deformed be double riveting heads structure anchor at upper surface Al plate an above la...

The rectangular assignment problem is a generalization of the linear assignment problem (LAP): one wants to assign a number of persons to a smaller number of jobs, minimizing the total corresponding costs. Applications are, e.g., in the fields of object recognition and scheduling. Further, we show how it can be used to solve variants of the LAP, such as the kcardinality LAP and the LAP with out...

Glass is a brittle material. Its use in constructing structural elements of civil engineering can still be considered as an innovative technique. In order to take a full advantage of its principal qualities (transparency, aestheticism, durability, etc.), architects are pushing the conception of glass structural elements towards the adoption of more and more slender elements, entailing necessari...
