A Reduced Iwan Model That Includes Pinning for Bolted Joint Mechanics

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 response of a jointed structure over a range of excitations once calibrated at a nominal load. The Iwan model, though, is not widely adopted due to the high computational expense of implementation. To address thi...

A GUI for a Software that Analyses a Composite Bolted Joint

FastComp is a computational tool for the determination of the forces that a composite bolted joint subjected to multiaxial loads supports until failure occurs. The main intention of the present work was the development of a graphical user interface (GUI) for the referred tool that allows its parameterization and the visualization of its output results. Using VTK The Visualization Toolkit, a com...

Fracture mechanics-based life prediction of a riveted lap joint

In this paper, three-dimensional modeling of the fatigue crack growth profiles was performed in a simple riveted lap joint. Simulation results showed that mode I was dominated on the one side of the plates and the crack straightly grew on this side, while the other side of the plates was in a mixed-mode condition and the crack propagation path was not straight on this side. Afterward, the fract...
