Thi Thuy Anh Vu and Dinh Duc Nguyen (2016) On the nonlinear stability of eccentrically stiffened functionally graded annular spherical segment. In: SW4PHD: the 2016 Scientific Workshop for PhD Students, 26 March 2016, Hanoi.
The nonlinear stability of eccentrically stiffened functionally graded (FGM) annular spherical segment resting on elastic foundations under external pressure is studied analytically. The FGM annular spherical segments are reinforced by eccentrically longitudinal and transversal stiffeners made of full metal or ceramic depending on situation of stiffeners at metal-rich or ceramic-rich side of the shell respectively. Based on the classical thin shell theory, the governing equations of FGM annular spherical segments are derived. Approximate solutions are assumed to satisfy the simply supported boundary condition of segments and Galerkin method is applied to study the stability. Numerical results are given to evaluate effects of homogeneous, dimensional parameters, outside stiffeners, elastic foundations to the stability of the structures.
