Abstract An investigation of dynamic behaviors a sandwich plate containing an imperfect two dimensional functionally graded (2D-FG) core surrounded by faces on two-parameter elastic foundation and subjected to moving load is carried out in this paper. The present solid composed porous 2D-FG covered homogenous layers. It assumed that the middle layer has micro voids dispersed uniformly unevenly ...

This paper proposes a nonlinear control architecture for flexible aircraft simultaneous trajectory tracking and load alleviation. By exploiting the redundancy, gust maneuver loads are alleviated without degrading rigid-body command performance. The proposed contains four cascaded loops: position control, flight path attitude optimal multi-objective wing control. Since kinematics not influenced ...

The primary resonance and nonlinear vibrations of the functionally graded graphene platelet (FGGP)-reinforced rotating pretwisted composite blade under combined external multiple parametric excitations are investigated with three different distribution patterns. FGGP-reinforced is simplified to cantilever plate reinforced by platelet. It novel simplify leakage airflow in tip clearance non-unifo...

The capabilities of a quadcopter in the hover mode for low-altitude sensing atmospheric turbulence with high spatial resolution urban areas characterized by complex orography are investigated. studies were carried out different seasons (winter, spring, summer, and fall), hovered immediate vicinity ultrasonic weather stations. DJI Phantom 4 Pro AMK-03 stations installed places studied territory ...

In this paper, static and dynamic stability analyses taking axial excitation into account are presented for a laminated carbon fiber reinforced polymer (CFRP) cylindrical shell under non-normal boundary condition. The condition is put forward to signify that both ends of the free one generatrix clamped. partial differential motion governing equations CFRP with derived using Hamilton principle, ...

This framework presents heat transfer analysis for swirling flow of viscoplastic fluid bounded by a permeable rotating disk. Problem formulation is made through constitutive relations Bingham model. Viscous dissipation effects are pre-served in the mathematical Entropy production which yet to be explored von-Karman non-Newtonian fluids. Having found similarity equations, these have been dealt n...
