It is well known that materials with a low m-value usually show no necking in a tensile test, i.e. very small post-uniform elongation, or even no post-uniform elongation at all.

Introduction Polyvinyl chloride is a thermoplastic polymer degraded during consumption, amorphous or weakly crystalline, main representative of the chloropolymer family, It is prepared from two raw materials: 57% sea salt (NaCl) and 43% oil; it is the only plastic material made up of more than 50% of raw material of mineral origin [1].

Therefore it could be seen that the application of new-type ceramic materials in ball screw will not only improve feed speed, but also obviously ameliorate axial contact stiffness and axial positioning accuracy of ball screw, etc.

Discrete Element Method (DEM) simulation is transforming the business of designing and optimizing equipment for the handling and processing of bulk materials.
The use of simplified particle shapes and contact interactions is needed in order to focus on the collective behavior of particles which is at the origin of many specific properties of granular materials.

While the poor spinnability is a significant problem to limit its utilization for rabbit hair, so using the staple fiber of rabbit hair to prepare the rabbit hair protein powder may be develop a great market potential for reuse of discarded fibers.many Researchers have focused their study on the production of superfine powders from wool fibers, and their work also suggested wool powder more extensive uses in cosmetics, medical materials, and industrial materials.
