The lightweight design of thin-walled curved structures as spherical shells are frequently implemented in architecture, aerospace, mechanical, automotive, nuclear, and defense structures. Under the transverse loads, may largely deform hence snap from one equilibrium position to other. Thus, this work aims develop a mathematical model computational solution investigate nonlinear bending snap-through behavior doubly auxetic metamaterial shell subjected transversal loading, for first time. is composed several layers through thickness, each layer manufactured copper (Cu) matrix reinforced with specified weight fraction graphene origami (GOAM). mechanical properties GOAM panel presented described by functions volume folding degree. Three types GOAM-distributions considered, which U-type, X-type, O-type. theoretical framework Kirchhoff–Love hypotheses thin von Karman type nonlinearity used derive governing equations. differential quadrature method (DQM) discretize space domain convert partial equation algebraic equations terms displacement field. An efficient incremental iterative procedure developed solve predict behavior. A conversion validation isotropic considered. Several numerical results conducted considering effects changing content, distribution pattern, degree, curvature thickness. For panels exhibiting behavior, increasing leads higher limiting load; however, instability gap enlarged.
