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.

The preparation and application of the cationic biopolymer based on xylan-rich hemicelluloses from agricultural biomass Junli Ren1,a,*, Xinwen Peng1,b, Feng Peng2,c, Runcang Sun1,2,d 1State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, China 2Institute of Biomass Chemistry and Technology, Beijing Forest University, China a,* renjunli@scut.edu.cn (corresponding author), bwenwenpeng1229@163.com, cfengpeng@bjfu.edu.cn, dynsun@scut.edu.cn Keywords: xylan-rich hemicelluloses; cationic biopolymers; papermaking; dry strength agent Abstract.
Recently, the conversion of hemicelluloses from agricultural and forest biomass to biodegradable and functional polymers and materials has been attracted increasing interests, such as quaternized hemicelluloses [2,3], carboxymethyl hemicelluloses [4,5], lauroylated hemicelluloses [6] and maleated hemicelluloses [7].
Therefore, appropriate chemical modifications provide the significant opportunity to endow hemicelluloses with the various valuable properties of hemicelluloses such as stronger, more elastic and more hydrophobic or thermoplastic properties, and the resulting products can be used as functional polymers [8] and selective membrane materials [9].
