The ratio of softening temperature (glass transition temperature) to elastic modulus ( T g / E ) is mainly determined by the limiting elastic deformation of an interatomic bond, which characterizes the transition of a structural microregion from an elastic into a viscous-flow state. In silicate ...
The theory of rubber elasticity relates the elastic modulus of unfilled amorphous rubber to the concentration of elastically effective strands. A theoretical relation between this concentration and the concentrations of potential entanglements, random tetrafunctional crosslinks, and chain ends was proposed ...
It is well known that the modulus G = r/( - 2) varies with deformation, thus deviating from the predictions of statistical theories of rubber elasticity which require it to be constant. It has also been found that there is a nonnegligible energy contribution to the elastic force. It is ...
Modeling of elastic properties and conductivity of partially sintered ceramics with duplex microstructure and different grain size ratio Correlations between relative Young's modulus and relative conductivity lie between upper and lower cross-property bounds. For single-phase materials the ... T Uhlirova...
Turgor regulation can result from (i) the decrease in the cell volume, (ii) the decrease in the symplast with respect to the apoplast volume, and (iii) the changes induced at the elastic modulus (Larher et al., 2009). In the present study, salt stress decreased significantly A. portu...
However, dynamic elastic wave dispersion was experimentally observed in polymer foams [164], and the actual elastic wave speed of a Voronoi foam was shown larger than that calculated using effective Young's modulus [70]. The elastic (and plastic) wave formed in the base material and propagating...
Data were obtained with regard to local carotid stiffness captured measured with the Young's elastic modulus (YEM). All participants underwent a commonly used Dutch intelligence test and resting-state eyes-closed magnetoencephalography (MEG). Five artefact-free epochs were analysed. The phase lag ...

In this study, it is investigated experimentally to find out a relation between the viscoelastic solid transition temperature and the adiabatic bulk modulus of lubricating oils. In the previous study, viscoelastic solid transition temperature is estimated from the occurrence of photo elastic effect by ...
An all-round theoretic analysis is carried out on maximum outreach of co-seismic strain changes of different magnitudes by using linear-elastic dislocation model.The longest propagation distances of certain co-seismic strain changes of different forms can extremely spread are given for the comparison ...
