Equivalent transverse shear stiffness of honeycomb cores

摘要: Abstract This work deals with the influence of geometry on equivalent transverse shear stiffness honeycomb sandwich plates. First, it presents analytical solution for a two-dimensional basic cell structures by two scale method homogenization periodic media. gives first order modulus structures. Then regular core is evaluated unite element using three-dimensional and The core, in general, depends plate. However, when depth large compared to hexagonal size, aspect ratio face panel thickness hexagon wall has little influence, approaches cellular Based numerical study, an improved lower limit cores proposed, local stress honeycombs presented.
