ラティスサンドイッチパネルの熱座屈に関する研究

抄録

In this study, the critical buckling temperature of a lattice sandwich panel was investigated by using FEM. In particular, the effects of geometric properties, for example a core height h, a core length L, and the number of cells N_c on the buckling temperature, were discussed. It was revealed that there are mainly two types of buckling modes of sandwich panels: global and local buckling mode. The critical buckling temperature for each mode can be estimated by using the equivalent shear modulus of the core, material properties of the panel and unit-cell length.
