A theoretical study on nonlinear in-plane buckling of shallow angle-ply laminated arches with elastic supports

This paper presents, for the first time, an analytical study on the nonlinear in-plane buckling of angle-ply laminated shallow arches with elastic supports under a uniform radial loading. To decouple internal forces and facilitate theoretical derivations, the nonlinear equilibrium path and buckling equation are established based on neutral plane formulation by using a virtual work method, from which the closed-form solutions for limit point...
