摘要: In this paper, thermal instability of shallow spherical shells made functionally graded material (FGM) is considered. The governing equations for a thin shell based on the Donnell–Mushtari–Vlasov theory are obtained. derived using Sanders simplified kinematic relations and variational method. It assumed that mechanical properties vary linearly through thickness. constituent to be mixture ceramic metal. Analytical solutions obtained three types loading including Uniform Temperature Rise (UTR), Linear Radial (LRT), Nonlinear (NRT). results validated with known data in literature.
