A general probabilistic fatigue crack growth prediction methodology for accurate and efficient damage prognosis is proposed in this paper. This methodology consists two major parts. First, the realistic random loading is transformed to an equivalent constant amplitude loading process based on a recently developed mechanism model. This transformation avoids the cycle-by-cycle calculation of fati...

This paper aims to experimentally and numerically probe fatigue behaviours lifetimes of novel GLARE (glass laminate aluminium reinforced epoxy) laminates under random loading spectrum. A mixed algorithm based on damage concepts three-phase materials was proposed for modelling progressive mechanisms life fibre metal (FML) To validate the algorithm, tests were conducted 2/1 3/2 subjected spectrum...

Earthquake can cause significant rock fracturing in either the short or long terms. A comprehensive analysis of mechanism is critical for assessing risks potential slope failures, landslides and avalanches seismic prone areas. This study employed 2D discrete element method (DEM) to investigate an intact 600 m base length 300 height, with explicit considerations material heterogeneity by random ...

In this study, mathematical models are developed to study and compare the operations of a fully reliable and an unreliable flexible manufacturing cell (FMC), each with a flexible machine, a loading/unloading robot, and a pallet handling system. The operation times, loading/unloading times, and material handling times by the pallet are assumed to be random. The operation of the reliable cell is ...

The present investigation presents a stochastic model for a flexible manufacturing system consisting of flexible machine, loading/unloading robot and an automated pallethandling device. We consider unreliable flexible manufacturing cell (FMC) wherein machine and robot operate under individual as well as common cause random failures. The pallethandling system is completely reliable. The pallet o...
