In this paper, the axisymmetric general solutions of transversely isotropic magnetoelectroelastic media are expressed with
four harmonic displacement functions at first. Then, based on the solutions, the analytical three-dimensional solutions are
provided for a simply supported magnetoelectroelastic circular plate subjected to uniform loads. Finally, the example of circular
plate is presented.

In this paper, the specific solutions of orthotropic plane problems with body forces are derived. Then, based on the general solution in the case of distinct eigenvalues and the specific solution for density functionally graded orthotropic media, a series of beam problem, including the problems of cantilever beam with body forces depending only on z or on x coordinate and expressed by z or x polynomial is solved by the principle of superposition and the trial-and-error method. 相似文献

INTRODUCTION In scientific and engineering problems, Volterra integral equations are always encountered and have attracted much attention (Christopher and Baker, 1977; Delves and Mohamed, 1985; Brunner and van der Houwen, 1986; Kress, 1989; Oja and Saveljeva, 2002; Maleknejad and Shahrezaee, 2004; Maleknejad and Aghazadeh, 2005; Zerarka and Soukeur, 2005). Generally, exact solutions are very difficult to find and solutions have been obtained for only some few special cases (Yan and … 相似文献

General solutions for coupled three dimensional equations of piezoelectric media were used in this work to obtain some analytical
solutions for free vibration of piezoelectric annular plates. These solutions not only satisfy the governing equations at
every point in the concerned region but also satisfy the prescribed boundary conditions at every point on the boundaries.
Therefore, they are three-dimensional exact. Numerical results are finally tabulated.

唐代今体诗的格律最完美。本文抓住唐代今体诗的格律作些探讨。今体诗从每行字数多、少的角度分有:五言(字),七言(字);今体诗从每首句数多、少的角度分有:绝句(每首四句),律诗(每首八句),排律(每首十句以上);今体诗从声调角度分有:平起首句入韵,平起首句不入韵,仄起首句入韵,仄起首句不入韵。把字数多、少与句数多、少结合起来分,这就是通常说的:五绝、七绝,五律、七律,五言排律、七言排律。 相似文献
