This article studies the role of temperature and nonlocality on low- high-frequency behaviors functionally graded sandwich nanoplates resting Winkler–Pasternak foundations. The small-scale effects are incorporated using nonlocal elasticity theory. rise in is characterized by uniform, linear, nonlinear distributions. governing equations solved Navier's solution, ensuring convergence frequencies at any mode sequence number. A comprehensive parametric study presented to elucidate various...
A novel nonlocal shear deformation theory is established to investigate functionally graded nanoplates. The significant benefit of this that it consists only one unknown variable in its displacement formula and governing differential equation, but can take into account both the quadratic distribution strains stresses through plate thickness as well small-scale effects on nanostructures. numerical solutions simply supported rectangular material nanoplates are carried out by applying Navier...
The main goal of this study is to further expand the ES-MITC3 for analyzing buckling characteristics functionally graded porous (FGP) variable thickness (VT) plates with sinusoidal distribution. was developed improve accuracy classical triangular elements (Q3) and overcome locking phenomenon while still ensuring flexibility in discretizing structural domain Q3. first-order shear deformation theory (FSDT) combination used due its simplicity effectiveness. Pasternak foundation (PF) a...
The main object of this paper is to further extend the MITC4 element analyse free vibration FG sandwich spherical shells with a honeycomb core (so-called h-FGSS shells) resting on Kerr foundation (KF). originates from three-dimensional continuum description degenerated shell behaviour which can be applied both thick and thin shells. consists an inner two different skin layers. FSDT used due its simplicity efficiency. KF includes three parameters as upper springer stiffness (kU), (kL), shear...
This paper introduces isogeometric analysis (IGA) based on higher-order shear deformation theory (HSDT) for vibration of sandwich plates resting Kerr foundation (KF). The include the ultra-light an auxetic honeycomb core layer and are reinforced by two laminated composite three-phase skin layers. governing equation is derived from Hamilton's principle. Newmark-β method applied to solve forced code in Matlab software. accuracy proposed verified through comparative examples. Additionally,...
Most of quadcopter operate in the outdoor environment where is often complex and unpredicted. In order to control unknown environment, it should be designed an excellent filter estimate complete state vector which illustrates movement rigid body. this paper, two filters such as Complementary Kalman are investigated compare performance. Quadcopter collect only measurements from a low-cost inertial measurement unit, IMU-MPU6050. The raw data put into system. simulations, these studied...
This research paper conducts a comprehensive investigation into the linear bending and free vibration of size-dependent functionally graded (FG) nanoplates using an improved first-order shear deformation theory (IFSDT). The present IFSDT offers enhanced representation precise computation normal stresses across thickness nanoplates. Notably, it not only ensures compliance with conditions on both upper lower surfaces but also eliminates need for conventional correction factor commonly employed...

Inverted pendulum (IP) is a single input-multi output (SIMO) nonlinear system that popular in laboratories of control engineering. In this paper, we propose structure the PID method – most industry - for cart and pole (C&P) system- kind IP. case, suitable can help input-single (SISO) linear controllers to balance well. By combination, be used stabilize model at equilibrium point. This controller proven work well simulation. Therefore, also present an experimental which created from...
