Bolted flange joints are widely used in pressure vessels and piping. With the increase in
installation of nuclear power plants, chemical industries and oil and gas transportation …

Threaded fasteners are one of the most commonly used connection methods for mechanical
structures. Its primary function is to generate appropriate clamping forces and fasten the …

The bolted spherical nodes are widely used as member joints of lattice shell structures. With
long-term service in a corrosive environment, the bearing performance degradation of these …

In order to investigate the relationship between torque and preload during the tightening
process by using torque-only control method, a new measuring device was designed in this …

Predicting the mechanical response of components requires simplifications and
idealizations that affect the fidelity of the results and introduce errors. Some errors …

The conventional engineering design of threaded fasteners applies a linear model
determining axial force from fastening torque and was found to be applicable only for …

The fatigue failure of the aircraft fasteners during service conditions are unavoidable. Most of
the published research works related to fatigue life estimation of threaded fasteners have …

In bolted joints, clamping force is determined by the material, geometrical dimensions, and
surface conditions of the assembly. There is a considerable risk of various industrial …

Background The incidence of hip fractures is increasing. Femoral intertrochanteric fractures
make up 50% of hip fractures and are treated by intramedullary nails. Implant breakage is a …

In order to study the effect of different bolts tightening sequences on the stress of bolts work-
piece, the finite element simulation and stress test experiments are adopted. Three types of …
