Thermal buckling of new model of functionally graded (FG) sandwich beams is presented in this study. Material properties and thermal expansion coefficient of FG sheets are assumed to vary continuously along the thickness according to either power-law (P-FGM) or sigmoid function (S-FGM) in terms of the volume fractions of the constituents. Equations of stability are derived based on the generalized higher-order shear deformation beam theory. Thermal loads are supposed to be constant, linear or nonlinear distribution along the thickness direction. An accurate form solution for nonlinear temperature variation through the thickness of S-FGM and P-FGM sandwich beams is presented. Numerical examples are presented to examine the influence of thickness ratio, the inhomogeneity parameter and the thermal loading kinds on the thermal buckling response of various types of FG sandwich beams.

AbstractA new method to design composite pressure vessels under strain and strength constraints using lattice structures is described. A graphical analysis is presented to find the optimum geometrical parameters of the rib for given fiber orientations. Minimum pressure vessel mass is determined from active execution of two constraints. Composite lattice structures are suggested as a new way of strain suppression among the commonly used methods such as (1) addition of extra plies, (2) use of composite material with a higher stiffness and (3) replacement of the circumferential layer with a second helical layer made of different materials. The experimental and analytical results of application of the method indicate that the vessel covered with composite lattice structures presented considerable weight savings with respect to traditional stiffened vessels.
