The resulting criteria weights are applied to the decision analysis where the fuzzy VIKOR approach is adopted which determines a compromise solution by using utility weight. 1 Introduction Product conceptual design is perhaps the most crucial stage in an engineering product development cycle, as nearly 70-80% cost and quality of the product will be determined during the concept design phase.

Non-linear Elastic Incremental Constitutive Model for Confined Concrete Xi’nan Jin1,a, Jianping Gao2,b and Jinglong Pan1,c 1School of Civil Engineering, Harbin Institute of Technology, Harbin 150090, China 2East China Jiaotong University, Nanchang, 330013, China aj-xn@sina.com, btmxgao@126.com, cpanjinglong@163.com Keywords: FRP; confined concrete; non-linear elasticity; constitutive model Abstract.
It seems impossible to establish an accepted constitutive model, which may be chosen appropriately in accordance with the mechanical characteristics, stress range and accuracy requirement of the structural engineering or analysis object.
Nowadays those non-linear elastic constitutive models obtained by using a regression analysis of test results are used most frequently in engineering practice.
The test was conducted in the Civil Engineering Laboratory of Harbin Institute of Technology using 200-ton and 500-ton hydraulic testing machine, following the relevant provisions of Standard Testing Methods for Concrete Structures (GB50152-92).
