Abstract. The aim of this study is to determine the influence of design factors of buttwelded sheet joints on the level of elastic stress concentration in joints. A nonlinear model was used to approximate the values of the elastic stress concentration factors obtained for different values of the geometric parameters for buttwelded sheet joints. This model is in good agreement with the values of the elastic stress concentration factors in the transition zone between the weld seam and base metal.
Key words: butt welded sheet joints, stressstrain state, elastic stress concentration factor, weld seams.
