Three-dimensional investigations of stress intensity factors in a thermo-mechanically loaded cracked FGM hollow cylinder
چکیده انگلیسی

This article focused on three-dimensional analyses of a functionally graded material cylinder which contains a semi-elliptical circumferential surface crack and subjected to thermo-mechanical loading (the internal pressure and the temperature gradient). The cylinder is assumed to be isotropic with exponentially varying elastic modulus through the thickness. The effect of non-uniform coefficient of thermal expansion 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 and the crack geometry have 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.
