Experimental Analysis of Dynamic Yield Strength of Material and Research on Its Numerical Method ZHAO Guangming1,2,a,MENG Xiangrui 1,2,b 1Key lab on safe and effective coal mining sponsored by Anhui province and ministry of education, Anhui University of Science and Technology, Huainan, Anhui 232001,China; 2School of Mining and Safety, Anhui University of Science and Technology, Huainan,Anhui 232001,China aemail:zhaogm@aust.edu.cn, bemail:xrmeng@aust.edu.cn Key Words: Tailor impact; the mesh-free method; the reproducing kernel particle method; the dynamic yielding strength Abstract.
Then analysis is conducted of the experiment results, together mesh-free simulation, indicating that the results obtained from the theoretical deduction, from the value simulation and from the experiments are mutually compatible. 1 Introduction The Tailor impact experiment is of great importance to any one who investigates dynamic material behaviors, especially the behaviors for materials with a high straining coefficient.
While Barenblatt [4] and Ting [5] applied the impact to the investigation into viscoplastic materials, Hutching[6] put forward a method for the estimation of the dynamic yielding strength for polymer.
And the method is also applicable to analysis of the dynamic mechanical properties of the material.

In this work, basic mechanisms of degradation of organic pollutants by ozone-based technologies in the presence of environmental materials as catalyst are described.
The objectives of this work are to present the research process on environmental materials with application of ozone-based technologies in removal of characteristic pollutants in pulp and paper effluents and the development trend of ozonation technologies with environmental materials as catalysts.
Ozonation of pulp mill effluent with environmental materials as catalysts In recent years, ozonation of pulp mill effluent in the presence of environmental materials as catalysts has been researched and better treatment efficiencies than single ozonation were obtained.
At present, application of catalytic ozonation process with environmental materials as catalyst in removal of characteristic pollutants in pulp and paper effluents is limited.
