The dielectric constant of elastomeric dielectric material is an
essential physical parameter, whose value may affect the
electromechanical deformation of a dielectric elastomer actuator. Since
the dielectric constant is influenced by several external factors as
reported before, and no certain value has been confirmed to our
knowledge, in the present paper, on the basis of systematical comparison
of recent past literature, we conducted extensive works on the
measurement of dielectric properties of VHB films, involving five
influencing factors: prestretch (both equal and unequal biaxial),
electrical frequency, electrode material, stress relaxation time and
temperature. Experimental results directly show that the dielectric

A vacant four-years PhD position is available. This PhD project will be done in Erasmus Medical Center (Rotterdam, NL) in collaboration with Delft University of Technology (Delft, NL) and is a part of a larger Dutch project on regenerative medicine and tissue engineering. The aim of the project is to generate cartilage from bone marrow derived stem cells in culture and evaluate them with molecular assays (Rotterdam) and mechanical assays (Delft). The culture protocol can be varied with oxygen level, tonicity, and active molecules.

Many people puzzle over the nomenclature of the pure shear test. They rightly point out that 1) the Pure Shear test piece is loaded in tension by extending the specimen in the axial direction, and 2) a shearing deformation, by definition, involves the lateral motion of parallel planes. They wonder where is the "shear"? and what does it mean to say that the shear is "pure"?  Here, we review the origins of the terminology. 

Can anybody suggest a good beginners book in micromechanics? I recently started working on ceramics and relatively new in this field. thanks.

i'need to  initial geometric imperfection of a localized buckling behavior of unstiffened thin plate will be analyzed. Code Abaqus finite element analysis can be used for this purpose. Since a default is not always in isolation, the interaction between several localized defects will be considered. A parametric study will be conducted on the effect due to the interaction by using an experimental and numerical analysis of variance.

thank you.
