3D Numerical modelling of residual stresses induced in finish turning of a fillet radius on a shaft made of 15-5PH
Abstract
The objective of this paper is to model the residual stress generation mechanisms induced during the finish turning of a fillet radius on a 15-5PH steel shaft. The model, based on the 3D thermo-mechanical equivalent loading method, is used to predict the continuous variation of residual stresses resulting from the continuous variation of the machined sections in the fillet radius. Finally, experimental tests are carried out to compare the numerical results with the residual stress measurements made by X-ray diffraction in some positions.
