Nonlinear Buckling of Fixed Functionally Graded Material Arches Under a Locally Uniformly Distributed Radial Load

Functionally graded material (FGM) arches may be subjected to a locally radial load and have different distributions leading nonlinear in-plane buckling behavior. Little studies is presented about effects of the type on FGM under in literature insofar. This paper focuses investigating behavior fixed uniformly distributed incorporating distributions. New theoretical solutions for limit point bifurcation loads equilibrium path that are three types derived. The comparisons between ANSYS results indicate accurate. In addition, critical modified geometric slendernesses related switches modes also It found affects as well significantly. increase with an slenderness, localized parameter proportional coefficient homogeneous ceramic layer decrease power-law index p arches.
