RESUMO

The problem of stress intensity factor (SIF) investigation for radial cracks in a thin hollow rotating functionally graded material (FGM) disk is of utmost interest. The disk is assumed to be isotropic with exponentially varying elastic modulus in the radial direction. The crack length and material gradation are the main parameters to be studied. The critical values of stress intensity factors in homogeneous and FGM disks are obtained. The results show that the SIF is highly dependent on the crack length and material gradation.
