Forced non-linear vibrations of a damped sandwich beam
(Elsevier, 1971-07-08)
Forced, damped, non-linear, low-frequency flexural motions of a clamped-clamped sandwich beam with thin face sheets and a soft viscoelastic core are examined experimentally and theoretically. The theory employed neglects ...
Inflight Aircraft Vibration Modes and Their Effect on Aircraft Radar Cross-Section
(University of Michigan. Radiation Laboratory, 1979-04)
Vehicle cruise: Improved fuel economy by periodic control,
(Elsevier, 1976-03)
It is shown that time-dependent periodic control can improve the fuel economy of vehicles in cruise. The time-dependent controls considered are relaxed steady-state (RSS) control, quasi-steady-state (QSS) control and ...
Transonic similarity solution for aligned field MHD nozzle flow
(Kluwer Academic Publishers; Noordhoff International Publishing ; Springer Science+Business Media, 1973-04)
The transonic flow near the throat of a converging-diverging nozzle of a gas with infinite electrical conductivity is considered. The magnetic field B is everywhere aligned with the velocity q so that the equations describing ...
The ground impulse generated by a plane fuel-air explosion with side relief
(Elsevier, 1979)
Detonations can be initiated in unconfined fuel-oxidizer clouds by blast waves of sufficient energy. The ground impulse generated by such detonations can cause considerable damage. An analytical theory is developed in the ...
Non-linear vibrations of three-layer beams with viscoelastic cores I. Theory
(Elsevier, 1976-05-08)
Approximate equations of motion are developed for large amplitude motions of three-layer axially restrained unsymmetrical beams with viscoelastic cores. The external force consists of a constant plus an oscillatory term. ...
Theoretical analysis of NO formation near the primary reaction zone in methane combustion
(Elsevier, 1976)
The complete kinetics of the CH4-air reaction are to study the details of NO formation near the primary reaction zone. The species and energy conservation equations are used in the analysis, however, diffusion and heat ...
Non-planar, non-linear oscillations of a beam II. Free motions
(Elsevier, 1976-08-08)
Steady and unsteady free motions of compact beams with fixed ends are examined. It is found that in certain situations planar motions are unstable to out-of-plane perturbations and whirling motions occur. In resonant cases ...
