Nonlinear Constitutive Equation and Elastic Constant of Rubber Material Chen Li1, a, Li Zhao1, b 1Taiyuan University of Science and Technology, Taiyuan, Shanxi 030024, China; atydz_lc@126.com, bzhaoli061801@163.com Keywords: nonlinear; rubber material; constitutive equation; strain energy function; elastic constant Abstract.
Introduction Rubber materials research has a long history in the past 50 years.
People tried to make authentic description, but because of its characteristics of complex molecules and the dual non-linear of materials and geometry, and it is very sensitive to the impact of the temperature, the surrounding medium, strain over time, loading rate and the strain, these makes the establishment of a precise mathematical model more difficult.
The results In order to fully evaluate the strain energy function that we derived, we fitted the experimental data which come from Treloar’s work of rubber materials about three kinds of deformation modes (uniaxial tension, biaxial tension, pure shear), the result is satisfactory.

Investigation for the Fracture Process of WCp/Cu Functionally Graded Materials under Three-Point-Bending Haiting Xia1,2,a,Rongxin Guo1,2,b, Feng Yan1,2, Hai Yu1,Yubo Zhang1 1Faculty of Civil and Architectural Engineering, Kunming University of Science and Technology, Kunming 650500,China 2Key Laboratory of Yunnan Higher Education Institutes for Mechanical Behavior and Microstructure Design of Advanced Materials,Kunming University of Science and Technology,Kunming 650500,China ahtxia2006@163.com, bguorx@kmust.edu.cn Keywords: Functionally Graded Materials, Fracture Process, Three-Point-Bending, Experimental Mechanics.
Introduction Functionally graded materials (FGMs) are known as materials in which a material composition varies gradually in some direction.
According to the knowledge of materials mechanics, the reason of the fracture of bending is that the maximum normal stress exceeds the ultimate stress of materials.
