Abstract

The paper deals with the analysis of stress and deformation conditions that occur in bolted joints with prestress. The stress and deformation states are significantly influenced by the grooves made in nuts. The grooves affect stress distribution in the nut – bolt connection and accordingly the shape of groove is very important for the knowledge of stress conditions in threads as well as in the whole bolted joint. In the paper is described a parametric study of grooves and corresponding stress states in bolted connections. Several types of grooves of different dimensions are studied. The grooves and corresponding results of computations can serve as material for better understanding of stress states inside joint assembly and consequently for better design of bolted joints. The computations of parametric studies were accomplished by the finite element method.
