Study on multi-axial mechanical properties of a polyurethane foam and experimental verification Shouhong Han1,2,a, Zhenhua Lu2,b, Yongjin Liu1,c 1Mechanical Technical Research Institute, Mechanical Engineering College, Shijiazhuang 050000, Hebei, China 2Department of Automotive Engineering, Tsinghua University, Beijing 100084, China ahanshouhong@163.com, blvzh@mail.tsinghua.edu.cn, cliuyongjin0325@163.com Keywords: polyurethane foam, multi-axial load, hydrostatic compression, phenomenological constitutive model, differential hardening model, self-similar yield surface Abstract.
Unfortunately, there exist only a few experimental data for multi-axial yield surfaces of any type of cellular solids, and standard experimental equipments and methods for hydrostatic compression on foam materials are few.
Therefore, from engineering practicability and economy point of view, the three key parameters on the elliptical yield surface (see Fig.1b), namely values in uni-axial compression, uni-axial tension and hydrostatic compression can be taken by experiments, and the yield surface model and its hardening law can be predicted accordingly.
Hydrostatic compression test was performed on the cylindrical specimens of diameter 38mm and height 30mm by a Hong Shan computer-controlled soil tri-axial testing machine in the department of hydraulic engineering, Tsinghua University.
A simple elastoplastic model for foam materials.

Nanofluids are created by dispersing nanoparticles of various materials (metal oxides, for example) in a base or carrier fluid.
In ferromagnetic materials, the complete magnetization typically remains aligned along the easy axis.

Realization CNC Controller Enable Machine Condition Monitoring Architecture Based on STEP-NC Data Model Firman Ridwan1,2,a and Xun Xu1,b 1Department of Mechanical Engineering, University of Auckland, New Zealand 2Department of Mechanical Engineering, Andalas University, Indonesia afrid003@aucklanduni.ac.nz, bx.xu@auckland.ac.nz Keywords: STEP-NC controller, Canonical Machine Command, Feed-rate Optimization Abstract.
This proved that the system is able to respond according to different workpiece material and spindle speed.
The key feature of the proposed NC program executor is the ability to perform adaptive feed-rate optimization by keeping a constant load within the machine tool’s capability.

Optimization and Application of Composite Index Method for Evaluation of Rock Burst Rating Zhang Jiayong1,2,a, Luo Xinrong1, Guo Liwen2 and Gong Xuemin2 1Faculty Safety Engineering China University of Mining and Technology, Xuzhou Jiangsu 221116 China 2College of Resources and Environment Hebei Polytechnic University, Tangshan Hebei 063009 China azjy815@163.com Keywords: Composite Index Method, Rock Burst, Weight, Analytic Hierarchy Process, Risk Index Abstract.
The most unstable coal bed is the material structural characteristics of the burst.
Therefore, to analyze the factors statistically, using the system engineering theory to find the influence degree of the factors in the process of the rock burst, then to obtain all factors’ weight based on the analytic hierarchy process, the product of the weight and the corresponding real index is the risk index and determined by every factor on the burst.
