AB - 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  investigation is focused to develop analytic expressions for stress intensity  factors at critical location of low pres-sure steam turbine disc.
