[ 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 ] - Effect of Material Gradient on Stresses of FGM Rotating Thick-Walled Cylindrical Pressure Vessel with Longitudinal Variation of Properties under Non-uniform Internal and External Pressure
The present paper provides a semi-analytical solution to obtain the displacements and stresses in a functionally graded material (FGM) rotating thick cylindrical shell with clamped ends under non-uniform pressure. Material properties of cylinder are assumed to change along the axial direction according to a power law form. It is also assumed that the Poisson’s ratio is constant. Given the exist...
[ 3 ] - 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...
[ 4 ] - 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...
[ 5 ] - An Analytical Solution for Temperature Distribution and Thermal Strain of FGM Cylinders with Varying Thickness and Temperature-Dependent Properties Using Perturbation Technique
This research presents temperature distribution and thermal strain of functionally graded material cylinders with varying thickness and temperature-dependency properties that are subjected to heat fluxes in their inner and outer layers. The heterogeneous distribution of properties is modeled as a power function. Using first-order temperature theory and the energy method, governing equations are...
