Abstract A detailed finite element (FE) model of M20 bolted joint is established. Using the FE model, loosening processes under different transverse vibration amplitude are simulated. The results show that there exists a critical amplitude. When smaller than amplitude, will not loosen. it larger is, faster loosens. Based on clamping force, nut rotation angle, bolt torsion deformation and slip t...

Due to the commonly eccentric connection on only one angle leg (bolted or welded), additional bending moments are acting member under compression axial force, leading a complex load-carrying behaviour with flexural and/or torsional buckling phenomena. Furthermore, type and size of rotational restraints at member's ends (provided by adjacent structure) significantly influence capacity these memb...

This paper aims at investigating the nonlinear behavior of a system which is consisting of two free-free beams which are connected by a nonlinear joint. The nonlinear system is modelled as an in-extensional beam with Timoshenko beam theory. In addition, large amplitude vibration assumption is taken into account in order to obtain exact results. The nonlinear assumption in the system necessities...

A detailed nonlinear finite element model was established based on completed experiments to investigate the behavior of a blind-bolted T-stub composite joint that connects beam concrete-filled square tube column. This accomplished by comparing experimental results and simulation using hysteresis curve, failure mode, plastic deformation strain development ensure reliability accuracy model. param...

The development of leakage and strength a metallic bolted flange joint are investigated in this work. Finite element analyses 2D 3D have been developed using ANSYS to study steel bolt with an aluminium gasket. pressure-penetration criterion (PPNC) has used model fluid propagation between the Validation was performed benchmark test, published joint; agreement results is excellent. Results showed...
