Mechanical Behavior of an Electrostatically-Actuated Microbeam under Mechanical Shock

In this paper static and dynamic responses of a fixed-fixed microbeam to electrostatic force and mechanical shock for different cases have been studied. The governing equations whose solution holds the answer to all our questions about the mechanical behavior is the nonlinear elasto-electrostatic equations. Due to the nonlinearity and complexity of the derived equations analytical solution are ...

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...

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.

Mechanical Properties of Engineering Materials

The engineering tension test is widely used to provide basic design information on the strength of materials and as an acceptance test for the specification of materials. In the tension test a specimen is subjected to a continually increasing uniaxial tensile force while simultaneous observations are made of the elongation of the specimen. The parameters, which are used to describe the stress-s...
