The mechanical performance analysis of grid structures with foam under the tests of quasi-static and dynamic loadings

Grid structure is a light and efficient structure. The composites have many excellent performances, such as that it can be designed excellently. This study mainly studies the grid structures with foam quadrilateral core-type. In this paper, the mechanical performance and the energy absorption properties were studied for the nine different kinds of core-type configurations, which undering quasi-static compressive test and impact test. And the optimize design of the structures could be obtained through comparing the mechanical properties and the energy absorption ability of the structures.
