lapped welded joint, stress concentration factor, method of non-planar cross sections, method of broken-planar cross sections, finite element methodAbstract
Subject, theme, aim. Subject of the research is the stress state of the lapped welded joint under loading. The aim is to describe stress state in the stress concentration zone. Stress concentration factor was caused by the geometry of welded joint.
Method or methodology. For researching stress state and stress concentrator factor of the lapped welded joint under tensile and bending forces was used method of the non-planar cross sections and finite element method.
Results. Expression that describing stress state and expressions for the stress concentration factor that was caused by tensile force and bending moment had been obtained by using the method of the non- planar cross sections. Also was obtained results using finite element method.
Field of application of the results. The results can be used for computations of the stress state of the constructions with lapped welded joints under static and cyclic loading.
