Abstract: An optical method is presented for the real-time monitoring of the bolt tightening process that provides the necessary clamping force in bolted assemblies. The method uses the 3D electronic ...

Abstract: A digital speckle pattern interferometry (DSPI) system is developed for the real-time measurement and monitoring of the out-of-plane surface deformation around a preloaded bolt head or nut. The ...

Abstract: The nonlinear plastic deformation behavior of a clamped bolted joint model under a separating service load is investigated using analytical, finite element, and experimental techniques. An ...

Abstract: The degradation of concrete structures is always accompanied by the formation of cracks. Crack monitoring is hence useful in assessing the “health condition” of the structure. In our previous investigation on an optical-fiber ...
