| Abstract: | Lattice sandwich structure,which is characterized by two thin face sheets and a lattice core sandwiched between them,is a novel kind of structure with the features of lightweight and multifunction.Due to its own structural form,the analysis of mechanical behavior of lattice sandwich structure is relatively complex.Converted discrete core to continuum homogenized material,the free vibration of all-composite tetrahedral lattice truss core sandwich beam is studied in this paper.Considering the bending deformat... |
