材料选择原则,在精密机械设计中材料的选择非常重要,尤其是在没有办法采取业界流传已久的参考设计的情况下,因为材料的选择不但需要满足设计的需求,而且与后续制造工艺(铸、锻、焊、热处理、加工方式、表面处理,等)密不可分;Ashby 揭示了一种材料选择的图形化工具,它可以帮助工程师在选择材料时同时比较两个参数,在材料...
Material indexDesign optimizationProduct designA key aspect in design optimization of a product or a system is the selection of materials that best meet the design needs, ensuring maximum performance and minimum cost. Ashby's approach, originally introduced for macro-systems and products, has been ...

Here Ashby's material selection approach is used to optimize the performance indices of RF-MEMS switch such as dielectric charging, stability, hold down voltage and RF performance. In this work, dielectric constant ( r ), electrical resistivity ( ρ ), thermal conductivity ( λ ), thermal ...
Conducting a materials selection exercise solely on PFRPs (i.e. excluding other materials and polymer composites sub-groups), Sapuan et al. [16], [17] have demonstrated the use of the analytical hierarchy process, a multi-criteria decision making method (Fig. 2), for analysing and ranking ...
The method is available as software* which allows even greater flexibility. The approach emphasizes design with materials rather than materials 'science', although the underlying science is used, whenever possible, to help with the structuring of criteria for selection. The first six chapters require...

for the dislocation reaction: An alternation method of measuring stacking fault energy can be applied with a material containing a stable array of dislocation nodes. When such node is imaged in dark field, then those dislocations for which will be out of contrast. In the dark field image of ...
To validate the results of material selection using Ashby's method, the top five selected materials for beam membrane and dielectric are applied on a MEMS switch and impacts of these materials on the electromechanical and RF performance have been presented. The results conclude that the Au and ...
