Abstract
In 2001, Naki Tutuncu and Murat Ozturk obtained analytical solutions for stress distribution of functionally graded material (FGM) cylindrical and spherical pressure vessels [COMPOS. PART. B-ENG, 32(8):683–686 (2001)]. The previous paper belongs to the classical study of elastic mechanics analysis of FGM, but their analytical expressions for the circumferential stress have some errors. The present letter corrects some analytical solutions in the classic problems of exact solutions for stresses in functionally graded pressure vessels. We prove correctness of the proposed analytical solutions by comparing with classical theory and finite element results.
