Post-buckling analysis of a nonlinear beam with axial functionally graded material
The postbuckling analysis of a modified nonlinear beam composed of axial functionally graded material (FGM) is investigated by a canonical dual finite element method (CD-FEM). The governing equation of the axial FGM nonlinear beam is derived through a variational method. The CD-FEM is adopted to find the nonconvex postbuckling configurations of the beam according to Gao's triality theory. Using duality transition, the original potential energy functional becomes a functional of deformation and...[Show more]
