Refined plate theory for free vibration analysis of FG nanoplates using the nonlocal continuum plate model

In this article, the free vibration behavior of nanoscale FG rectangular plates is studied within the framework of the refined plate theory (RPT) and small-scale effects are taken into account. Using the nonlocal elasticity theory, the governing equations are derived for single-layered FG nanoplate. The Navier’s method is employed to obtain closed-form solutions for rectangular nanoplates assum...

Experimental and Numerical Free Vibration Analysis of Hybrid Stiffened Fiber Metal Laminated Circular Cylindrical Shell

The modal testing has proven to be an effective and non-destructive test method for estimation of the dynamic stiffness and damping constant. The aim of the present paper is to investigate the modal response of stiffened Fiber Metal Laminated (FML) circular cylindrical shells using experimental and numerical techniques. For this purpose, three types of FML-stiffened shells are fabricated by a s...

Effect of Thermal Environment on Vibration Analysis of Partially Cracked Thin Isotropic Plate Submerged in Fluid

Based on a non classical plate theory, an analytical model is proposed for the first time to analyze free vibration problem of partially cracked thin isotropic submerged plate in the presence of thermal environment. The governing equation for the cracked plate is derived using the Kirchhoff’s thin plate theory and the modified couple stress theory. The crack terms are formulated using simplifie...

NATURAL VIBRATION ANALISIS OF CLAMPED ANNULAR ISOTROPIC SECTOR SHIP HULL PLATE USING EKM

The natural vibrations of clamped annular isotropic sector plates are analyzed using the Extended Kantorovich Method (EKM). A conformal mapping is used to transform a sector with identified geometry to a rectangular plate which the solution is available in literature and solved by Dalaei and Kerr [1] using EKM. The developed iterative scheme converges very rapidly to the final result. The obtai...
