Abstract: Mechanical and thermal behaviors of the bolted joint subjected to thermal load are analyzed using axisymmetric FEM, where the effects of thermal contact resistance at the interface and heat ...

Abstract: When evaluating the strength of threaded fasteners under external loads, stress area is commonly used. However, in order to elucidate the mechanical behavior of bolted joints more rigorously and ...

Abstract: Distinctive mechanical behavior of bolted joints is caused by the helical shape of thread geometry. Recently, a number of papers have been published to elucidate the strength or loosening ...

Abstract: Fatigue failures of bolted joints frequently lead to serious accidents in machines and structures. It is well known that fatigue failure is likely to occur around the first thread root of the ...

Abstract: A bolted joint is widely used for the structures and machines subjected to thermal load, such as pressure vessels, internal combustion engines, brake disks, etc. In order to accurately evaluate ...

Abstract: It is well known that a large amount of scatter in bolt preloads is observed when bolting up a pipe flange connection, especially in the case of using a spiral wound gasket. In this study, ...

Abstract: Mechanical behavior of bolted joints during the tightening process with torque control is analyzed by FEM as elastic plastic contact problems. Three-dimensional analysis was conducted employing ...

Abstract: The tightening operation with a bolt heater has advantages surpassing those of other tightening methods. Currently, a bolt heater is mainly applied to tighten huge bolts that cannot be clamped ...
