Abstract |
Porous functional gradient material (FGM) sandwich structures are widely used in various
fields. However, the study of their dynamic response under multiple blast excitations is lacking. This
paper develops a nonlinear dynamic model of a porous FGM sandwich hyperbolic panel based on
Winkler-Pasternak elastic foundation and von Kármán strain-displacement relations. The model
comprehensively incorporates the effect of material inhomogeneity, geometric nonlinearity, and timevarying blast loading for the first time. Subsequently, a numerical solution strategy is constructed by
coupling the finite difference method in the spatial domain with the Newmark method in the time
domain. In addition, the effects of porosity distribution, geometric parameters, foundation stiffness,
and blast load parameters on the structural response frequency, deflection amplitude, and damping
performance are investigated. Results reveal that sandwich panels with uniformly distributed porosity
in the FGM exhibit superior dynamic stability and blast resistance under repeated explosive loads. The
findings can provide theoretical support and engineering guidance for the blast-resistant design and
intelligent optimization of novel porous FGM sandwich composite structures. |
