Parametric Formula for Stress Concentration Factor of Fillet Weld Joints with Spline Bead Profile

Dynamic Stress Concentration Factor in the Strip Plate with Fillet

Dynamic and static stress concentration factors ao, and as generated at a fillet part are observed by photoelastic method, and the comparison between two different factors is carried out. Next, the reflection coefficient A is calculated using the height of incident and reflected waves measured by the strain gauge. As the result, following relationship a= ( I+ A )as is derived experimentally. Th...

The Weld Profile Effect on Stress Concentration Factors in Weldments

The assessment of beneficial effects of weld geometry modification methods is considered in this paper. Since all these methods significantly increaese weld toe radius, its influence on stress concentration factors is analised. The dependance of theoretical stress concentration factors vs. weld toe radius was determined by using both finite element analisys and photoelasicity method for various...

distribution of stress concentration factors along the weld toe of tubular kt-joints in truss bridges

many research works have been accomplished so far on the computation of stress concentration factors (scfs) for various types of tubular joints. almost all these studies have focused on values of the scf at the saddle and crown positions, and they have ignored the hss at other locations along weld toe. however, scf distribution is very important for predicting the fatigue crack growth, determin...

Weld Magnification Factor Approach in Cruciform Joints Considering Post Welding Cooling Medium and Weld Size

The objective of this research is to develop an experimental-theoretical analysis about the influence of the cooling medium and the geometry of the welding bead profile in fatigue life and the associated parameters with structural integrity of welded joints. A welded joint with cruciform geometry is considered using SMAW (Shielded Metal ArcWelding), plates in structural steel ASTM A36 HR of 8 m...
