the failure mode and effects analysis (fmea) is a widely used analytical technique that helps to identify and reduce the risks of failure in a system, component, or process. one important issue of fmea is the determination of the risk priorities of failure modes. risk ranking is produced in order to prioritize the focus on each of the failure modes that are identified. in this study, we applied...

Meshfree Galerkin approximations in both two and three dimensions have been used in simulations of dynamic shear band propagation in an asymmetrically impact-loaded prenotched plate. Failure mode switching and failure mode transitions, which have been reported experimentally, are replicated in numerical computations. For intermediate impact speed (25 m=s < V 6 30 m=s), the numerical results sho...

Introduction: The use of dental ceramics has increased due to their beauty and biocompatibility. The aim of this study was to evaluate the effect of hydrofluoric acid concentration and etching time on microtensile bond strength (μTBS) of the Enamic and Suprinity ceramics. Material & Methods: In this in vitro study, two hydrofluoric acid (HFA) concentrations of 5% (A) and 10% (B) were used at t...

This paper presents a methodology for the assessment of ductility and strength capacities in low-rise buildings. This method utilizes the characteristics of force-displacement for the lowest story level or considers the weakest story in any given low-rise building for its primary analysis. Calculations are based on two levels of earthquake motions, namely strong earthquakes (PGA=0.3 g), and ver...
