Abstract

Based on Mindlin plate models and Kirchhoff plate models, this study was concerned with the wave propagation characteristics in thick conventional and auxetic cellular structures, with the objective to clarify the effects of negative Poisson's ratio, shear factor and orthotropic mechanical properties on the dynamic behaviors of thick plates. Numerical results revealed that the predictions using variable shear factor in Mindlin plate models resulted in high wave frequencies, which were more significant for plates with negative values of Poisson's ratio. The present study can be useful for the design of critical applications by varying the values of Poisson's ratio.
