Journal Club Theme of May 2012: Hierarchical and Quasiperiodic Phononic Crystals and Metamaterials
Submitted by gtg627e on Tue, 2012-05-01 18:00.Following last month’s blog by Mahmoud on the role of structure in the design of materials capable of controlling the propagation of mechanical waves, I would like to delve into the characteristics of the structure itself. The propagation of mechanical waves can be controlled via scattering induced by a material’s structure.The propagation of waves for example is significantly disturbed when their wavelength and direction become correlated with the medium’s structure. This is known as Bragg scattering and can be achieved simply by embedding voids or inclusions (of different physical properties) in a material [1].

Large, uni-directional actuation in dielectric elastomers achieved by fiber stiffening
Submitted by Jiangshui Huang on Tue, 2012-05-22 17:46.Cylindrical actuators are made with dielectric elastomer sheets stiffened with fibers in the hoop direction. When a voltage is applied through the thickness of the sheets, large actuation strains are achievable in the axial direction, with or without pre-straining and mechanical loading. For example, actuation strains of 35.8% for a cylinder with a prestrain of 40%, and 28.6% for a cylinder without pre-strain have been achieved without any optimization. Furthermore, the actuation strain is independent of the aspect ratio of the cylinder, so that both large strains and large displacements are readily actuated by using long cylinders.

Complex interplay of nonlinear processes in dielectric elastomers.
Submitted by Jian ZHU on Wed, 2012-05-16 22:18.A combination of experiment and theory shows that dielectric elastomers exhibit complex interplay of nonlinear processes. Membranes of a dielectric elastomer are prepared in various states of prestretches by using rigid clamps and mechanical forces. Upon actuation by voltage, some membranes form wrinkles followed by snap-through instability, others form wrinkles without the snap-through instability, and still others fail by local instability without formingwrinkles.Membranes surviving these nonlinear processes are found to attain a constant dielectric strength, independent of the state of prestretches. Giant voltage-induced stretch of 3.6 is attained.

Objective Stress Rates in Finite Strain of Inelastic Solid and Their Energy Consistency
Submitted by bazant on Sat, 2012-05-12 01:38.In many practical problems of solid mechanics, it is sufficient to characterize material deformation by the small (or linearized) strain tensor. But there are also many problems where the finiteness of strain must be taken into account. These are of two kinds: 1) Large nonlinear elastic deformations possessing a potential energy (exhibited, e.g., by rubber), in which the stress components are obtained as the partial derivatives of potential energy; and 2) inelastic deformations possessing no potential, in which the stress-strain relation is defined incrementally and the stress increment or rate must be formulated objectively (i.e., independently of coordinate rotations). The present paper reviews the latter kind.
