Functionally graded materials (FGMs) are the advanced materials with varing properties in dimensions. These are made of two or more constituent phases with continuous and smoothly varying composition in preferred directions. The properties of material depend on the spatial position in the structure of material. These materials are gaining attention for biomedical application as biomaterials owi...
در این پایان نامه راه حل نیمه تحلیلی برای بررسی رفتار ترموالاستیک و خزشی دیسک های دوار دارای تقارن محوری ساخته شده از مواد ساختار یافته منظم (functionally graded materials) ارائه می شود. برای این منظور، معادلات تعادل و سازگاری و تنش و کرنش حاکم بر رفتار خزشی اینگونه دیسک ها استخراج شده و سپس با استفاده از معادله ساختاری theta projection معادلات خزش برای دیسک های دوار ساخته شده از مواد ساختار یا...

In this research, thermal buckling of thin rectangular plate made of Functionally Graded Materials (FGMs) with linear varying thickness is considered. Material properties are assumed to be graded in the thickness direction according to a simple power law distribution in terms of the volume fractions of the constituents. The supporting condition of all edges of such a plate is simply supported. ...
the current study presents a new analytical method for buckling analysis of circular plates with constant thickness and poisson’s ratio, made of functionally graded material subjected to radial load. governing equations are based on energy method for thin plates. the boundary conditions of the plate are assumed to be simply supported and clamped. the stability equations were obtained by using c...
Based on fundamental equations of the elasticity theory, a unified higher-order shear deformation theory is developed for bending and free vibration analysis functionally graded (FG) microplates with porosities. The modified strain gradient employed to capture size effects. Bi-directional series hybrid shape functions are used solve problems. Several important effects including thickness-to-mat...
Stress analysis of functionally graded composite plates composed of ceramic, functionally graded material and metal layers is investigated using 3-D finite element method. In FGM layer, material properties are assumed to be varied continuously in the thickness direction according to a simple power law distribution in terms of the volume fraction of a ceramic and metal. The 3-D finite element mo...
in this paper, the effect of autofrettage process parameters on the ultimate pressure that functionally graded spherical vessel can tolerate are investigated. fgm properties and autofrettage pressure are considered as important parameters. assumptions are variation of properties of fgm in radial direction, the residual stress in the absence of bauschinger effect with the operation of variable m...
