| Abstract [eng] |
Paper presents the results of investigation of the stress concentration at the groves of the inner side of cur-vature for the curved beams of circular cross-section. This investigation supplements the earlier work for curved beams of trapezoidal cross-section and enables the evalua-tion of the suitability and versatility of the established equations for the calculation of the stress concentration factors. The paper also presents the investigation results of the evolution of stress triaxiality and plastic strain under the increasing load. It was found that the stress triaxiality factor is higher at the beginning of the plastic deformation comparing to one calculated under the elastic stress state. However, when the plastic strain covers the entire cross section of the beam the stress triaxiality reduces. |
