[ 1 ] - جابه جایی ها و تنش ها در پوسته های استوانه ای توخالی جدارضخیم چرخان FGM تحت فشار به کمک تئوری تغییر شکل برشی مرتبه سوم
در این مقاله به منظور تحلیل الاستیک پوستههای استوانهای تشکیل شده از مواد هدفمند (FGM)، معادلات دیفرانسیل حاکم بر استوانههای جدارضخیم چرخان FGM تحت فشار در حالت متقارن محوری به کمک تئوری تغییر شکل برشی مرتبه سوم (TSDT) استخراج و حلّ عمومی آنها برای شرایط انتهایی دو سرگیردار ارائه شده است. سپس با انجام مطالعه موردی و همچنین ارائه یک حلّ عددی، توزیع جابهجایی و تنش حاصل از حلّ تحلیلی به کمک تئور...
[ 2 ] - Semi Analytical Analysis of FGM Thick-Walled Cylindrical Pressure Vessel with Longitudinal Variation of Elastic Modulus under Internal Pressure
In this paper, a numerical analysis of stresses and displacements in FGM thick-walled cylindrical pressure vessel under internal pressure has been presented. The elastic modulus is assumed to be varying along the longitude of the pressure vessel with an exponential function continuously. The Poisson’s ratio is assumed to be constant. Whereas most of the previous studies about FGM thick-walled p...
[ 3 ] - Displacements and Stresses in Pressurized Thick FGM Cylinders with Varying Properties of Power Function Based on HSDT
Using the infinitesimal theory of elasticity and analytical formulation, displacements and stresses based on the high-order shear deformation theory (HSDT) is presented for axisymmetric thick-walled cylinders made of functionally graded materials under internal and/or external uniform pressure. The material is assumed to be isotropic heterogeneous with constant Poisson’s ratio and radially varyi...
[ 4 ] - Nonlinear analysis of radially functionally graded hyperelastic cylindrical shells with axially-varying thickness and non-uniform pressure loads based on perturbation theory
In this study, nonlinear analysis for thick cylindrical pressure vessels with arbitrary variable thickness made of hyperelastic functionally graded material properties in nearly incompressible state and clamped boundary conditions under non-uniform pressure loading is presented. Thickness and pressure of the shell are considered in axial direction by arbitrary nonlinear profiles. The FG materia...
[ 5 ] - Nonlinear analytical solution of nearly incompressible hyperelastic cylinder with variable thickness under non-uniform pressure by perturbation technique
In this paper, nonlinear analytical solution of pressurized thick cylindrical shells with variable thickness made of hyperelastic materials is presented. The governing equilibrium equations for the cylindrical shell with variable thickness under non-uniform internal pressure are derived based on first-order shear deformation theory (FSDT). The shell is assumed to be made of isotropic and homoge...
