Experimental Techniques for Fatigue Analysis of a Small Wind Turbine Blade
Abstract: During the life span, a wind turbine blade experiences variety of the forces. These forces include gravitational force, centrifugal force, tangential force, thrust force, etc. Thrust force and gravitational forces create edgewise bending stress while the tangential forces (wind pressure) create flapwise bending stress. Centrifugal forces generate direct stress in the wind turbine blade. Most of the wind turbine blades fail due to bending in the flapwise direction. These induced …

Enhancement of Cable Profile and Deck Arrangement in Cable Stayed Bridge A Review
Abstract: Cable-stayed bridges are usually self-anchored structures and therefore offer a good solution at locations where the soil conditions are not good and as a consequence the cost of the foundations for an earth-anchored structure like a typical suspension bridge would become excessive. To overcome these problems, it is necessary to find a new type of material in lieu of steel. Fiber reinforced polymer (FRP) has many excellent properties, such as …

Effect of Notch on Low Cycle Fatigue of AA 2024-T351
Abstract: Notch effect on low cycle fatigue of AA 2024-T351 was investigated. Decreasing notch curvature leads to less cyclic hardening. Values of fatigue strength exponent (b) and fatigue ductility (c) for notch specimens were out of range of metallic materials. The SEM examination showed multi-crack origins with secondary cracks and a large final-fracture zone for unnotched specimens, while there was small final fracture zone close to the center of the specimen …
