When the machine is operating, the high speed rotation may lead to the cutters flying out of the rest, so not only both sides of the header (includes flattening roller) should be covered and the both sides of disc-type rests should be wrapped by flexible materials to prevent injuring the crowd on the both sides when the cutter accidentally fly off.

Solution to this problem lies with bringing the subsurface layer into a state of higher ductility while retaining its hardness at high enough level, for instance by nanostructuring which serves both for reducing the strain localization scale level and increasing the volume of material subject to deformation [1, 2].
Material and Research Technique The hard metal of composition 75%WC + 14% (Ti, Ta, Nb)C - 11% Со has been used as a material for study.

Study on the coupling system is quite difficult for fabric and machinery are two kinds of quite different materials.
In fact, with development of manufacturing and in the demand of improving machine performance, anisotropic metal materials have been applied in mechanical engineering.
The technology of modeling and simulating this kind of materials is quite mature.

Since members of different materials are connected at the joints, the internal force mechanism of SRHSHPC frame joints is complicated than those in either reinforced concrete structure or steel structure.
Joints with lower axial compression ratio and lower concrete strength grade possess better hysteretic energy performance.This project is sponsored by National Natural Science Foundation of China (Grant No. 50378080) and the Educational Office of Shaan'xi Province in China.
