Inspired by an idea to construct bionic materials, these microstructures are simplified by a porous composite model with cross-fiber layer by layer.
Figure 2 shows the torn of chafer shell .We can see that this is a kind of orthogonal layered laid fiber-reinforced composite material, unidirectional fiber composition one-way layer, two adjacent layer direction Angle approximate 90 ° present.
Chafer carapace can be seen as a N-layer orthogonal composite panels, the stress concentration factor as a weighted average of each single stress concentration factor, namely: （2） Where: N is the overlay on the total number; M is the ply orientation number; Ni for the direction of the i repeat number of plies; Ki is stress concentration factor of the i-th layer. 4 Material models Campaniform sensillum of chafer is simplified to the pore on the orthogonal layered laid fiber reinforced plate.Study the bionic mechanical properties by this form , introduced a unidirectional fiber-reinforced plate with 1mm width , 1mm long, and set up a series of φ0.06mm porous with a certain arrangement of the rule .Up and down on both sides of the composite by Y displacement constraint，in the X axis to withstand even stress load.

Introduction FGMs are heterogeneous composite materials usually made from a mixture of metals and ceramics, By gradually varying the volume fraction of constituent materials, their material properties exhibit a smooth and continuous change from one surface to another, thus eliminating interface problems.
With the increased use of these materials, it is important to understand the nonlinear behavior of functionally graded plates under pressure load.
The set of materials considered is alumina and aluminum.
Modeling studies applied to functionally graded materials.
