Vibration Computational of Visco-Elastic Plate with Sinusoidal Thickness Variation and Linearly Thermal effect in 2D
Keywords:
Vibration, Frequency, Taper Constant, Thermal Effect, Plate.Abstract
The attention of recent technology has been directed toward faster and larger, and therefore the
needs for more flexible and lighter structures are obvious. This trend has increased the practical importance
of dynamic analysis in addition to the classical static analysis, and the numerical evaluation of vibrational
characteristics of structural elements has become an important part of the design process. The free,
transverse vibration of isotropic square plate is investigated in the paper. The thickness of the plate is varying
sinusoidal linearly in 2D and temperature linearly in 2D:
Rayleigh-Ritz technique has been employed to obtain fundamental frequencies of first two modes. The effect
of structural parameters such as taper constants and thermal gradient with clamped boundary condition has
been taken. Numerical results thus obtained are shown graphically.
