Free vibration of square plate with temperature effect.

In modern engineering, researchers/scientists are very keen to know first few modes of vibration because it provides how system/structure behaves under vibration. In this paper, author computed the natural vibration of non homogeneous tapered square plate. Here tapered means that plate's thickness varies linearly along x-axis. Here non homogeneity arises in the plate's material due to simultaneous variation in density (circular variation) and Poisson's ratio (exponential variation). Temperature variation on the plate is viewed bi-parabolic along the axes. Rayleigh-Ritz technique is applied to obtain the frequency equation and vibrational frequency modes under different combination of parameters. The findings of the papers are presented in tabular form. [ABSTRACT FROM AUTHOR]
