摘要: Abstract Dynamic buckling of functionally graded materials truncated conical shells subjected to normal impact loads is discussed in this paper. In the analysis, material properties are assumed be thickness direction according a simple power law distribution terms volume fractions constituents. Geometrically nonlinear large deformation and initial imperfections taken into account. Galerkin procedure Runge–Kutta integration scheme used solve governing equations numerically. From characteristics dynamic response obtain critical shell B-R criterion. research results it can found that gradient have significant effects on FGM shells.
