This method is an extension of the finite element-transfer matrix (FE-TM) method. In...
Mathieu equation is a 2nd order differential equation with a periodically modulated coefficient relevant to the squared natural frequency. It describes the parametric excitation of oscillation, 2D vibration in elliptic coordinates, wave propagation in periodically varying medium, etc. Depending on the param...

To find the secondary field, we have to use the solution of Laplace’s equation that decreases as the distance from the ellipsoid increases. Let us assume that the second type of solution has the form (3.124)Us(ξ,η,ς)=BG1(ξ)F2(η)F3(ς). This presentation is very natural ...
Moreover, we propose a formal gradient flow structure for this equation with the kinetic energy as the natural energy functional. This is important in order to draw the connection with the aggregation equation (1.1), via a formal Taylor expansion which we describe in Sect. 1.3. As a ...

where ζ is termed the damping ratio and is defined as the ratio of the actual damping in the system to that which would produce critical damping.ωn is the undamped natural frequency of the system and k, again, is the system gain. The time-domain solution depends on the magnitude of ζ...
those of analytical method,the magnitude of the natural frequency was dependent on the value of velocity of the elastic wave induced by the free vibration of the beam,and the vibration of Timoshenko beam under each natural frequency was the coupled vibration caused by bending and shearing ...
Here we consider for definiteness the solutions of the homogeneous Dirichlet problem in a bounded domain Ω∈ R N and compare the standard concept of a variational (or energy) solution with the recently introduced concept of an entropy solution, which seems natural in the L 1 theory. For our...
