STATIC ANALYSIS AND FREE VIBRATION ANALYSIS OF THE PYRAMIDAL LATTICE SANDWICH STRUCTURE BASED ON LAYERWISE/SOLID-ELEMENTS METHOD
The layerwise/solid element method（ LW/SE） was used to study the static and free vibration problems of lattice sandwich structure under different boundary conditions. First,the layerwise theory was used to analyze the behavior of the shell of composite face sheets,and the three-dimensional solid ele...

| description | The layerwise/solid element method（ LW/SE） was used to study the static and free vibration problems of lattice sandwich structure under different boundary conditions. First,the layerwise theory was used to analyze the behavior of the shell of composite face sheets,and the three-dimensional solid elements were employed to obtain the governing equations of the core. And then,based on the governing equations of the face sheets and core,the finial governing equation of sandwich structure was assembled by using the compatibility conditions,which was used to ensure the compatibility of displacements at the interface between face sheets and core. The numerical results of the proposed method were compared with those obtained from the 3 D elastic model developed in finite element software,and good agreements are achieved. Furthermore,a series of numerical analyses are conducted to further explore the effects of the thickness of the face sheets on the static responses and free vibration responses of composite lattice sandwich structures. |
