WebAug 12, 2024 · It is important, while analysing the stress concentration phenomenon in welded joints with fillet welds, to know the effect of particular geometrical parameters on stress concentration factors Ktt and Ktb. Two typical situations appearing while designing welded structures are considered below. Webstress concentration is always a serious problem in ductile materials that are subjected to cyclic loads because the ductility of the material is not effective in relieving the …

WebA stress concentration is defined as high localized stress, compared to the average stress of the body, and is typically found in a region that has an abrupt geometric change or … WebFor the commonly used pressure vessel material Q345R, the theoretical formulas of stress concentration factor (SCF) and fatigue life of welded joints were derived. A finite element analysis model was established to systematically study the theoretical SCF and fatigue life of the joint. The results show that the theoretical SCF increases by 45% with the increase … WebStress concentration factors calculated by finite element model analysis were found to be higher than those interpolated from experimental data, but with more consistent values … jds imports lubbock
