One fundamental paradigm in engineering is to break a structure into simpler components in
order to simplify test and analysis. In the numerical world, this concept is the basis for finite …

Bolted joints play a more and more important role in the structure with lighter weight and
heavier load. This paper aims to provide an overview of different experimental approaches …

Motivated by the current demands in high-performance structural analysis, and by a need to
better model systems with localized nonlinearities, analysts have developed a number of …

Structures with bolted joints are known to exhibit amplitude-dependent shifts in the natural
frequency and damping of its modes that are challenging to model accurately. These two …

Aeroengine manufacturers face fundamental limitations when correlating experimental
dynamic analysis with finite element method models. The source of inconsistency between …

Bolted flanges in aero-engine casings exhibit a nonlinear response when subjected to
forced vibration. The current models for the structural dynamic analysis of bolted flanges are …

Bolted joints are prevalent in most assembled structures; however, predictive models for
their behavior do not exist. Calibrated models, such as the Iwan model, are able to predict …

The joint structures, such as flanges with bolts and curvic-couplings, are commonly applied
in aero-engine rotors. Those joints tend to loosen when subjected to heavy load, and the …

Considering the non-uniformly distributed contact pressure, this study presents a new
contact characteristic parameters (contact stiffness and damping) model for bolted joint …

Bolted joints are a significant source of damping and nonlinearity in built up structures. In the
micro-slip regime (ie when the bolts do not slip completely) the log of the damping tends to …
