Study on Vibration and Stability Analysis of Thick Rectangular Plates Section

This paper is the second part of free vibration and stability analysis of thick isotropic and orthotropic plates. The support condition CCCC and CCFC support was considered by applying the alternative II theory based on polynomial shape function. The work was based on the application of the formulation earlier derived using Ritz method. The frequency values of the first mode and critical loads obtained were compared with those obtained using first order shear deformation theory. For span to depth ratio of 10, the fundamental linear frequency for orthotropic CCFC plate corresponding to modulus of elasticity ratios (E1/E2) of 10, 25 and 40 were 0.00312Hz, 0.00373 Hz and 0.00398Hz.  &nbsp
