In general, these materials exhibit certain amount of scatter in their properties due to different factors.
Recently, a class of composite materials viz., FGMs has drawn much attention in many engineering applications.
The mechanical response of systems depends on external stimuli and the materials used for their fabrication.

Sports Equipment Based on High-Tech Materials Song Tao East China Jiaotong University Sports Institute, Nanchang Jiagnxi, 330013 Keywords: new materials; sports; application Abstract.
The 1960 Olympic Winter Games, making Snowboard made artificial materials using a French player, won the championship, this caused the sports scientists great interest in making ski. 70 years later, with the development of material science, scientists have developed a new material for ultra high molecular weight polyethylene, ski, snowboard made of this material with no water, greatly improvement glide performance.
New Materials Applied In Free Gymnastics Mat Gymnastics equipment using some new materials modern achievements of science to improve, to increase elasticity, toughness, more suitable for athletes to play to their potential, more conducive to innovation and reduce sports injury.

Simultaneously, the service behavior of the bamboo/steel slabs is pecfect and there is execllent composite effect between the two different materials.
And the strain is basically the same at the interface of the two kinds of materials.
Bamboo/steel composite beam composites with two different plate materials by structural adhesive.
Because the thickness of composite beam's flange plate is large relatively, the strain gradient changes intersection between surfaces of two different materials.
