[ 1 ] - Large Amplitude Vibration Analysis of Graphene Sheets as Resonant Mass Sensors Using Mixed Pseudo-Spectral and Integral Quadrature Methods
The present paper investigates the potential application of graphene sheets with attached nanoparticles as resonant sensors by introducing a nonlocal shear deformation plate model. To take into account an elastic connection between the nanoplate and the attached nanoparticle, the nanoparticle is considered as a mass-spring system. Then, a combination of pseudo-spectral and integral quadrature m...
[ 2 ] - Semi-Analytical Solution for Free Vibration Analysis of Thick Laminated Curved Panels with Power-Law Distribution FG Layers and Finite Length Via Two-Dimensional GDQ Method
This paper deals with free vibration analysis of thick Laminated curved panels with finite length, based on the three-dimensional elasticity theory. Because of using two-dimensional generalized differential quadrature method, the present approach makes possible vibration analysis of cylindrical panels with two opposite axial edges simply supported and arbitrary boundary conditions including Fre...
[ 3 ] - ارتعاشات غیرخطی صفحات حلقوی با ضخامت متغیر پله ای با خواص اورتوتروپیک
در این مقاله ارتعاشات غیرخطی صفحات حلقوی با ضخامت متغیر پله ای با خواص اورتوتروپیک مورد بررسی قرار گرفته است. پس از بدست آمدن معادلات حاکم بر صفحه،فرض وجود مودهای هارمونیک واستفاده از روش ریتز-کانتورویج،موجب حذف متغیر زمان در روابط تعادل شده و معادلات دیفرانسیل نسبی حاکم بر صفحه به یک جفت معادله دیفرانسیل معمولی غیرخطی(معادلات فون کارمن) که به صورت مسئله مقدار ویژه می باشد،تبدیل گردیده است . آن...
[ 4 ] - Effects of Geometric Nonlinearity on Stress Analysis in Large Amplitude Vibration of thin Circular Functionally Graded Plates With Rigid Core
Abstract In this paper , the nonlinear the nonlinear free and forced axisymmetric vibration of a thin circular functionally graded plate with rigid core is formulated in terms of von-Karman’s dynamic equation , and a semi-analytical approach is developed.Functionally graded material (FGM) properties vary through the thickness of the plate.FGM s are spatial composites within which material prop...
