Introduction Concrete is a man-made material, and there are micro cracks in it before bearing its loads.
SFHSC is a new composite material, and it can be obtained by joining steel fiber into high strength concrete (HSC).
After loaded, the stress of the material with bigger plastic zone in front of the crack leading edge increases slowly with deformation increasing quickly, so strain or displacement can be used as a physical quantity to represent the fracture of material.

In addition, e0a represents a nonlocal parameter where e0 and a are the material constant and an internal characteristic length, in that order.
The local or classical continuum mechanic cannot predict accurately the behavior of nanoscale materials.

The Analysis of dynamic viscoelastic properties of regenerated cellulose at different temperature and humidity Ming-shan YANG Department of Material Science and Engineering, Beijing Institute of Petrochemical Technology, Beijing 102617, P.R.China; yangms001@126.com Keywords: regenerated cellulose; dynamic viscoelasticity; absorption and transition Abstract: The effects of temperature and relative humidity on regenerated cellulose had been investigated in detail in the present work.
Introduction Cellulose is the very important material not only because it is the richest natural polymer in nature, but also because it is a renewable material and energy resource.
Recently, fairly active studies on cellulose have been carried out all over the world and have involved in the current Hi-Tech fields such as ultrafiltration membrane, dialyzed and virus-filtrated membrane, bioactive and functional materials, etc.[1-5].

Ring rolling has many advantages, such as high utilization of material, wide range of product application, high efficiency and low cost and so on [1].
It will cause waste product, waste materials and increase cost if the roughcast construction, material selection and technological parameter is unreasonable.
The material trademark of ring is 16Mn.
