The Theory of Diffusion in Strained Systems
Author: Louis A. Girifalco
Publisher:
ISBN:
Category : Crystals
Languages : en
Pages : 1082
Book Description
A general theory of solid-state diffusion in strained systems is developed on a molecular-kinetic basis. The theory predicts that for simple strains the diffusion coefficient is an exponential function of the lattice parameter and that the rate of change of the diffusion coefficient with strain is linearly related to the interatomic forces. It has also been shown that for plastic flow the diffusion coefficient is a linear function of strain rate. All the conclusions are confirmed by the data available in the literature.

Some Static Longitudinal Stability Characteristics of an Overlapped-type Tandem-rotor Helicopter at Low Airspeeds
Author: Robert J. Tapscott
Publisher:
ISBN:
Category : Downwash (Aerodynamics)
Languages : en
Pages : 666
Book Description
Flight measurements of some longitudinal static stability characteristics with an overlapped-type tandem-rotor helicopter at low airspeeds are presented. The data show that a critical amount of longitudinal control is required to maintain trimmed flight at certain combinations of airspeed and rate of descent. Estimates based on theoretically predicted interference effects indicate that the front rotor downwash acting on the rear rotor could cause variation of the longitudinal moments of the same order of magnitude as the measured variation.
