Electrical and Mechanical Performance of Zirconia-Nickel Functionally Graded Materials

In the present work, six-layered (Zirconia/Nickel) functionally graded materials were fabricated via powder metallurgy technique (PMT). The microstructure, fracture surface and the elemental analysis of the prepared components were studied, and their linear shrinkage, electrical conductivity, fracture toughness and Vickers hardness were evaluated. The results show that the linear shrinkage of t...

The Characteristics of Innovative, Mechanical Products

Many new products fail upon introduction to the marketplace, but a few products are exceptionally successful, earning innovation awards and other benchmarks of success. To better understand the features of those innovative products, 197 award-winning products are analyzed to identify the characteristics that distinguish those products from the competition. For the analysis, a set of product-lev...

Mechanical properties of cellular materials

Materials with cellular structure occur widely in nature. This seminar discusses the mechanical models of two and three dimensional cellular solids. We introduce the honeycomb-like structure of wood and the foam-like structure of the trabecular bone. The third example of cellular material, glass sponge Euplectella sp., is presented as well.
