With the increasing complexity of engineering geological conditions, problem tensile-shear failure bolts is becoming more serious. Accurate modelling performance bolted rough joints subjected to load essential for support design. In this paper, based on theoretical criteria bolt failure, mechanical model Pile element in FLAC3D program modified, and accuracy modified verified by numerical experi...

This article discusses the issue of force behavior in a pre-tensioned bolt that is part symmetrical flange connection, loaded with an operating load parallel to axis. The first describes being dealt detail. next offers brief description generally known theoretical approach solution, and also outlines limitations this approach. followed by analysis working analyzed device, using Finite Element M...

Fretting fatigue is a damage process that occurs when two surfaces in contact with each other are subjected to relative micro-slip, causing reduced life respect the plain case. has now been studied deeply for over 50 years, but still no univocal design approach universally accepted. This review presents literature study involves three main types of mechanical joint affected by fretting (press-f...
