Influence 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 کاملThe Fatigue Strength of Fillet Welded Connections
This report describes a study of the fatigue behavior of fillet welded joints stressed perpendicular to the weld line. The study included an experimental phase in which the stiess-life and cracking behavior of load and nonload carrying fillet weld joints was determined. This experimental study concentrated on the fatigue behavior in the transition region between high and low cycle fatigue 3 5 (...
متن کاملRelation between Residual Stress and Fatigue Strength for Electron Beam Welded Joints of Sheet Metal
Residual stresses in welds significantly affect the fatigue strength and stress corrosion crack resistance of the weld joint, and therefore, numerous studies have been made about the effects. The residual stress induced by electron beam welding (EBW) has also been researched in various approaches, but many of the study reports dealt with thick plates (50 mm or thicker) only.1–5) This was becaus...
متن کاملComparison of the stress intensity factor of load-carrying cruciform welded joints with different geometries
The investigation of fatigue strength needs an accurate solution and reliable values of the stress intensity factor (SIF). In this study, SIF of load-carrying cruciform welded joints has been evaluated using finite element method (FEM), and compared with the available solutions from literature. Load-carrying cruciform welded joints with isosceles triangles and non-isosceles triangle fillet weld...
متن کاملAnalysis of Spot Weld Joints by Ultrasonic Inspection, Fem and Residual Stress Measurements
The present work seeks to determine the parameters for approval, through ultrasonic techniques, of spot welded joints of low carbon steel sheets. For such experience the mechanical behavior of a spotwelded joint was characterized under fatigue, in load cycles ranging from zero to 14 kN, on sheets of 1.5 mm thickness, joined by three spot welds of 7.5 mm of medium diameter, being the distance am...
