چکیده    The present study focuses on three-dimensional analyses of a thick walled functionally graded material cylinder,containing a longitudinal semielliptical internal surface flaw,and is subjected to an internal pressure and a rotational speed. the cylinder is assumed to be isotropic with exponentially varying elastic modulus through the thickness. the effect of wall thickness on the distribution of stress intensity factor is also studied. the results which are normalized for the advantage of non-dimensional analysis show that the material gradation,the crack geometry and wall thickness have a significant influence on the amount and distribution of stress intensity factors. numerical results are given to assess the safety of the fgm and homogeneous cracked cylinder. the study is valuable to engineering applications. © 2016 jordan journal of mechanical and industrial engineering. all rights reserved.
