In this article, an exact levy solution is presented for bending analysis of a functionally graded (FG) annular sector plate. The governing equilibrium equations are obtained based on the classical plate theory. Introducing an analytical method for the first time, the three coupled governing equilibrium equations are replaced by an independent equation in term of transverse deflection. This equ...

In this study, the analysis of transverse vibrations of rectangular plate with circular central hole with different boundary conditions is studied and the natural frequencies and natural modes of a rectangular plate with circular hole have been obtained. To solve the problem, it is necessary to use both Cartesian and polar coordinate system. The complexity of the method is to apply an appropria...

this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...

In the present study, a semi-analytical model based on small-amplitude wave theory is developed to describe fields around single gravity-type cylindrical open fish net cage. The cage may be submerged different depths below free-water surface. modelled as flexible porous membrane, and deflection of chamber expressed by transverse vibration equation strings. velocity potential expanded in form Fo...

We study the deflection by gravity of a circular elastic disk deposited on rigid support. The axisymmetric induces compressive orthoradial stresses which leads to wrinkling instability above critical threshold dimensionless force. this combination experiments, numerical simulations and analytical tools, with particular focus role geometry. show that aspect ratio is crucial parameter controls bo...

This study was numerically focused on the non-linear behaviour of glass fibre reinforced polymer (GFRP) concrete beams with different amounts transverse reinforcement. The mid-span deflection beam cannot effectively be restricted using higher amount flexural GFRP bars, owing to their low deformability factor. So, use high reinforcement ratio is proposed decrease and crack widths. Following this...

The study concerns the transverse deformation behavior of a penetrator surrounded by sabot in deformed gun barrel. In barrel, occurs due to problems such as deflection gravity, or geometric tolerance caused manufacturing process. This causes structural instability and affects out-of-gun barrel movement. addition, safety is affected supporting penetrator. finite element method was used evaluate ...

This work is dedicated to studying the influence of yaw angle on wake characteristics a 2.5 MW utility-scale wind turbine using large-eddy simulations with turbine's blades and nacelle parameterized as actuator surfaces. Four different angles are simulated, i.e., $\gamma=0^{\circ},10^{\circ},20^{\circ},30^{\circ}$ for three tip-speed ratios $\lambda = 7,8,9$. Similarities observed both time-ave...
