Free vibration and snap-through instability of FG-CNTRC shallow arches supported on nonlinear elastic foundation

作者：

Highlights：

• The nonlinear vibration and snap-buckling behaviors of composite arches reinforced with CNTs are analytically investigated.

• A perturbation method is applied to obtain the nonlinear static/dynamic response of the nanocomposite arch in thermal field.

• Interaction of the temperature-dependent composite arch with a hardening/softening elastic foundation is taken into account.

• The nonlinear equations of motion are established in the framework of a general higher-order shear deformation theory.
