2. Bending, Vibration and Buckling of Laminated Composite Plates Using a Simple Four Variable Plate Theory
Abstract In the present study, a simple trigonometric shear deformation theory is applied for the bending, buckling and free vibration of cross-ply laminated composite plates. The theory involves four unknown variables which are five in first order shear deformation theory or any other higher order theories. The in-plane displacement field uses sinusoidal fu

3. Transverse Motions of Rectangular Plates Resting on Elastic Foundation and Under Concentrated Masses Moving at Varying Velocities
AbstractThis study concerns the dynamic characteristics of a prestressed isotropic, rectangular plate continuously supported by an elastic foundation and carrying accelerating mass M. Closed form solutions of the governing fourth order partial differential equations with variable and singular coefficients are presented. For the two-dimensional plate problem,

4. The effect of viscoelasticity on creep behavior of double-lap adhesively bonded joints
The effect of viscoelasticity of epoxy adhesive on creep behavior in the adhesive layer of a double-lap joint is studied in this paper. The joint is comprised of three elastic single isotropic adherend layers joined by an epoxy adhesive that is under shear loading. Prony series is used to modeling the relaxation modulus of epoxy adhesive. The differential eq

6. Sintese de nanotubos de carbono por CVD utilizando catalisadores à base de ferro e molibdênio suportados em matrizes cerâmicas
Molybdenum is known for its synergistic effect in the synthesis of carbon nanotubes (CNs) by chemical vapor deposition (CVD method). When added to typical catalysts like iron, nickel, and cobalt, even in small quantities, it is increases the yield of these nanostructures. The presence of Mo also has an influence on the type and number of CN walls formed. Alt

8. Andreev transport in double quantum dots coupled to superconductor and ferromagnetic leads / Transporte por reflexão de Andreev em pontos quanticos duplos acoplados a eletrodos supercondutores e ferromagneticos
In this work we studied the quantum transport in two hybrid nanostructures composed of double quantum dots (DQD)s coupled to superconductor (S) and ferromagnetic (F) leads. The first nanostructure, denoted by F - QDa - QDb - S, is composed of a ferromagnet, two quantum dots, and a superconductor connected in series. In the second nanostructure, denoted by (

12. Estudo de conformação de cerâmicas à base de zircônia para aplicação em células a combustível do tipo óxido sólido / STUDY OF TAPE CASTING OF YTTRIA STABILIZED ZIRCONIA FOR APPLY IN SOLID OXIDE FUEL CELL
The hydrogen economy has been risen as new option for supply the growing global demand for energy. A fuel cell is an electrochemical device able to use hydrogen as a energy source. Carbon dioxide (CO2) emission is very low so it is ecologically friendly, once energy is produced by a reaction of hydrogen and oxygen. The production of energy from hydrogen fuel
