Finite Element Modeling Method of Honeycomb Sandwich Based on Engineering Application |
| |
| Abstract: | A method of finite elements modeling called "Combination Element" is concluded through the analysis on mechanical properties of honeycomb sandwich. And it is proved effective compared with the theoretical analysis of the typical loading honeycomb sandwich structure and the results of strength test of the typical honeycomb panel. The problem of strength design of composite material honeycomb sandwich located in aircraft movable wing-box is solved. Meanwhile, the method provides references for other simi-lar structures within the field of aeronautic and aerospace industry. |
