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.

Magnesium and its alloys seem to be among the most appealing materials to design biodegradable stents.
Among the solutions proposed to overcome this drawback, the adoption of degradable materials coupled with new shapes of the device seems to be very promising.
