Bending, buckling and free vibration analyses of shallow-to-deep FG curved sandwich beams using a global–local refined shear deformation theory

This paper investigates the bending, vibration, and buckling behaviour of functionally graded (FG) curved sandwich beams using a global–local refined shear deformation theory. Material properties these are varied through thickness according to power-law distribution. A beam element with combination Hermite cubic quadratic Lagrange shape functions is developed solve problems. The obtained results compared from finite software (ABAQUS), other higher-order theories. It can be observed that present model predict accurately static, responses both shallow deep FG arbitrary boundary conditions.
