Functionally graded triply periodic minimal surface (FG-TPMS) structures are known as bio-inspired structures. They possess some remarkable advantages such porous with high inter-connectivity, mathematically controllable geometry features and smooth surfaces. As another advantage, FG-TPMS can be fast numerously manufactured by 3D printing technology. Nevertheless, modeling these is a challenging task. This paper investigates static bending free vibration behaviors of shells. The proposed formulation established upon isogeometric analysis (IGA) first-order shear deformation shell theory (FSDT). governing equations discretized Galerkin weak form numerically solved using non-uniform rational B-Spline (NURBS) basis functions. Exact geometries described via NURBS A fitting technique used to compute the mechanical characteristics materials. We investigate shells considering three types cell which primitive (P), gyroid (G), I-graph wrapped package-graph (IWP), six porosity distribution patterns. present solutions verified reference ones in literature. Effects boundary, type geometry, pattern, length-to-radius thickness ratios on rigorously studied. Especially, many numerical results first this paper.
