RANGE OF CHANGE OF THE CONCENTRATION IN WELDS FORMED IN THE DIRECTION OF LOADING. CONSTRUCTIVE RECOMMENDATIONS FOR OPTIMIZATION

Ivan Kolarov

The aim of study is to investgate the concentration in an angular weld formed in the direction of the externally applied force depending on the construction of the welded elements. Seams for joining products by overlapping were investigated. The goal is achieved by conducting a virtual experiment to determine the stress state in sections of the weld between elements with different structural configuration. The elements are modeled in a computer environment and joined by a seam with a maximum seam leg according to current regulations in the field. The concentration coefficient at the end of the compound was calculated from the obtained results.
