Effect Of Stress Concentrations On Fatigue Of Composite And Metallic Structures, Ross Henry Falen
Effect Of Stress Concentrations On Fatigue Of Composite And Metallic Structures, Ross Henry Falen
Masters Theses
"The complex shapes of hydrokinetic turbine blades can include part features such as a fillet, step, or hole. Situations can arise where two part features, such as a hole and a fillet, may be in close proximity which can introduce stress concentrations within the blade structure, adversely affecting the structure's life. Because the interaction between the part features isn't well known, fatigue data is needed to determine the proper analysis.
In this thesis, two separate topics are discussed and investigated. The first topic deals with stress concentrations in hydrokinetic turbine blades. Several blade designs were tested and improved upon to …
