Numerical Determination of Stress Concentration and Material Yielding Factors for Welded Joints

Stress concentration factors and factor of material yielding determination for characteristic welded component applied in shipbuilding is described. Optimal shape of hot spots due to stress distribution by finite element analysis was analysed. Spreading of yielding zones by changing both nominal stress and radius of roundness has been presented. It is evident that factor of material yielding for nominal stress greater than one half of yield strength becomes constant.
