In this paper, two kinds of vibrations are considered for a composite Timoshenko rotor: longitudinal-torsional vibration and two plane transverse one. The kinetic and potential energies and virtual work due to the gyroscopic effects are calculated and the set of six governing equations and boundary conditions are derived using Hamilton principle. Differential quadrature method (DQM) is used as ...

In chip-multiprocessors (CMPs) the network-onchip (NoC) carries cache coherence and data messages. These messages may be classified into critical and non-critical messages. Hence, instead of having one interconnect plane to serve all traffic, power can be saved if the NoC is split into two planes: a fast plane dedicated to the critical messages and a slower, more power-efficient plane dedicated...

The paper is concerned with the derivation of failure criteria for anisotropic materials through a simple extension of the Mohr Coulomb failure criterion and embracing the critical plane concept. We revisit the classic problem of determining the macroscopic strength of a rock specimen with an initial structural anisotropy in relation to the directions of externally applied principal stresses. M...

In this paper, the thermal buckling analysis of a circular plate made of FGM materials with actuator/actuator piezoelectric layers based on neutral plane, classical plate theory and first order shear deformation plate theory is investigated. Reddy's model is assumed for material properties of FGM plate. Plate under the thermal loading, nonlinear temperature rise through the thickness and clampe...

Let Q be a nonbipartite quadrangulation of the projective plane. Youngs [13] proved that Q cannot be 3-colored. We prove that for every 4-coloring of Q and for any two colors a and b, the number of faces F of Q, on which all four colors appear and colors a and b are not adjacent on F , is odd. This strengthens previous results that have appeared in [13, 6, 8, 1]. If we form a triangulation of t...

We investigated the behavior of the spin-triplet superconductor Sr2RuO4 ( T(c) approximately 1.5 K) under the magnetic fields parallel to the quasi-two-dimensional plane. The upper critical field H(c2) exhibits a clear fourfold anisotropy of about 3% at 0.35 K. Furthermore, we detected an additional transition feature below H(c2) in both the ac susceptibility and the specific heat. These second...

We have solved the governing equations for the buckling of rectangular functionally graded plates which one of its edges has small non-zero deflection and moment. For the case that the material properties obey a power law in the thickness direction, an analytical solution is obtained using the perturbation series. The applied in-plane load is assumed to be perpendicular to the edge which has no...
