Abstract
In the present work,based on the nonlinear dynamics software AUTODYN,we performed a three-dimensional simulation of the instability process of the aluminum honeycomb sandwich panels under blast loading.By establishing the solid model of aluminum honeycomb sandwich panels with different parameters,we studied the dynamic response of the front and back sheets under the TNT impact and the instability deformation in the plastic stage.The results achieved from our calculation show that with the increase of the thickness of the aluminum honeycomb panel,the height and thickness of the aluminum foil,the final residual deformation of the aluminum honeycomb panel under blast loading is obviously reduced and its deformation-resistance ability is enhanced.For the aluminum honeycomb panels with different cell shapes but the same relative density,the distinction of the panels' final residual deformation under blast loading is not significant because there is little difference in "inertia effect" under the uniaxial compression condition.关键词
