The volume expansivity
is readily calculated from the density function according to Equation (8).
Lyapunov exponents versus expansivity
and sensitivity in cellular automata.
The critical paraphernalia bearing upon the Lettres portugaises is in a state of ongoing expansivity
, both in scope and dimension.
Furthermore, it appears that thermal expansivity
effects dictate the phase separation process in polybutadienes of varying microstructure.
The reason is that functionally gradient materials can develop and relax the extra stress which caused by the different thermal expansivity
and are supposed to improve the welding strength and constant capacity.
In either case, there is a large expansivity
mismatch between that of the chip (6 ppm/K) and TPI (20 ppm/K).
In the range of purely elastic strains, both W and Q of each FRP component in stretching (+) and contraction (-) cycles should behave reversibly, the sign of Q being determined by that of the linear expansivity
In addition to the obvious significance of the time dependence of the volume following various thermal treatments, the thermal expansivity
as such represents one of the key variables in this context.
The thermal expansivity
and compressibility could be related to the free volume fraction and positive deviations from linearity were noticed in the former.
Compared with engineering plastics (EPs), PLCs have greater mechanical strength and thermal stability, frequently lower melt viscosity, exhibit lower flammability and thermal expansivity
, are more stable in vacuum, and resist chemical and radiational degradation (18-20).
Both aspects will affect the thermal expansivity
and mechanical properties of the film, which in turn are related to the stress in the film after curing.
Thus the two functions currently available for comparisons of any kind are the thermal expansivity
and the bulk modulus.
Roth, "Unpublished Observations of Density and Expansivity
," in J.
This conclusion is consistent with our previous thermal conductivity and expansivity
measurements on the same series of blends .
Nevertheless, a peculiar behavior is observed for the transverse expansivity
above the [T.
