The transformer as a system consists of several components and it is absolutely essential that the integrity of all these components individually and as a system is ensured. A transformer is a complex three-dimensional electromagnetic structure, and it is subjected to variety of stresses, viz. dielectric, thermal, electrodynamic, etc.

      Active aeroelastic control is a recently emerging technology aimed at providing solutions to a large class of problems involving the aeronautical/aerospace flight vehicle structures that are prone to instability and catastrophic failures, and to oscillations that can yield structural failure by fatigue. In order to prevent such damaging phenomena to occur, the linear/nonlinear aeroelastic.   Nanomaterials (i.e. material structure with at least one dimension smaller than nm, following the definition given by the US National Nanotechnology Initiative, USNNI) are at the frontier of materials science due to their remarkable, and in some cases novel, properties [].This results in particular from the surface-to-bulk ratios that are much higher than those of coarse particles (e.g.

Thermal Buckling of the Concrete Rectangular Thin Plate. Analysis of shell-type structures subjected to time-dependent mechanical and thermal loading. Abstract. The objective of this chapter is to give an overview of experimental and theoretical approaches to analyze the behavior of materials and structures subjected to mechanical loading and “high-temperature” environment.

Publisher Summary. Composite multistorey building structures are highly redundant and their floor systems exhibit high in-plane stiffness. When a compartment fire occurs beneath the floor, the behavior of the floor system is dominated by restraint to thermal expansion, with middle surface heating and through thickness gradients causing quite different effects.

A method to predict the dynamic behaviour of anisotropic truncated conical shells conveying fluid is presented in this paper. It is a combination of finite element method and classical shell theory.

Erasmo Carrera (Polytechnic of Turin, Italy) Most of known theories for the analysis of beam- plate- and shell-type structures have been originated by intuitions of eminent Scientists such as Leonardo Da Vinci, Euler, Bernoulli, De Saint Venant, Poisson, Cauchy, Kirchhoff, Love, Reissner, Mindlin, Vlasov, etc.

In the present work, to improve the mechanical flexibility and ion release, the composite fiber was coated with a soft, thin layer consisting of poly(d,l-lactic-co-glycolic acid) (PLGA). A coaxial electrospinning technique was used to prepare a cotton-wool-like material comprising “core-shell”-type fibers with a diameter of ~12 µm.

The primary goal of Advanced Mechanics of Composite Materials is the combined presentation of advanced mechanics, manufacturing technology, and analysis of composite materials.
