Fracture mechanics analysis of damaged turbine rotor discs using finite element method

Abstract: This paper presents evaluation fracture mechanics parameters in low pressure turbine components. Critical locations such as keyway and dovetail area are experiencing stress concentration leading to crack initiation. Stress intensity factors were evaluated using the J-Integral approach available within ANSYS software code. The finite element method allowed the prediction of the point of crack initiation and the crack propagation using the orientations of the maximum principal stresses. Special attention in this… Show more

“…In recent decades, the progress in rapid computer technology has stimulated many numerical simulation developments and applications to predict the residual stresses and deformations of welded structures in their early design phase [6][7][8][9][10]. Due to frequent application, T-joint fillet welded joints have attracted the attention of many researchers in recent years.…”
