Fatigue Life of Wind Turbine Structural Components
Modern mega watt class wind turbines are exposed to high and complex loads. At the same time the aim is to realize light weight and optimized structures. Compared to other industries the design lifetime of a wind turbine is very long. Applying simulation tools for the predictions of fatigue life is therefore essential. This paper presents the approaches for fatigue anaylses used in the wind ind...
متن کاملInfluence of Residual Stress on Fatigue Life of Hot Forged and Shot Blasted Steel Components
Hot forging is a common manufacturing process for the production of large quantities of engineering components. Residual stresses are developed in forged components as a result of various aspects of the manufacturing process, including subsequent cooling, and heat treatment. Residual stresses can significantly affect the deformation and fatigue failure of materials. Hot forged EN15R steel bars ...
متن کاملEstimating the fatigue stress concentration factor of machined surfaces
In this study the effects of surface texture on the fatigue life of a high-strength low-alloy steel were evaluated in terms of the apparent fatigue stress concentration. An abrasive waterjet was used to machine uniaxial dogbone fatigue specimens with specific surface quality from a rolled sheet of AISI 4130 CR steel. The surface texture resulting from machining was characterized using contact p...
متن کاملThe Basic Relationship between Residual Stress Profile Patterns and Fatigue Life of Precision Machined Surfaces in Rolling Contact
The characteristics of residual stress (RS) profiles and their effects on rolling contact fatigue life for precision turned and ground surfaces with a white layer (WL) are very controversial. The key findings of this study are: (a) The basic RS profiles by a sharp tool can be fundamentally changed by a turned WL but not a ground WL; (b) The hook shaped RS profile of a turned surface may have ab...
متن کاملFatigue Life Prediction of Rivet Joints
Strength reduction in structures like an aircraft could be resulted as cyclic loads over a period of time and is an important factor for structural life prediction. Service loads are emphasized at the regions of stress concentration, mostly at the connection of components. The initial flaw prompting the service life was expected by using the Equivalent Initial Flaw Size (EIFS) which has been re...
