Laboratory studies often use short hold times at the maximum temperature (minutes), in contrast to power reactors, which operate isothermally for months between cooling cycles. When ensuring the memory effect is maintained, differential...

... Though the definition of equilibrium moisture content of porous materials is straightforward from the point of view of equilibrium thermodynamics, experimental determination of this quantity may not always be easy. Many factors play roles from an experimentalist's point of view. Hysteresis...

.... The phenomenological approach is based on the stiffness degradation of the composite with incremental load steps. The analytical approach is based on the shape of the unload/reload hysteresis loops. continuous fiber ceramic composite tension test unload/reload thermal exposure hysteresis residual stress...

... mechanical analysis. The time dependence of the glass transition causes hysteresis phenomena and physical aging. Strain effects on the observation of the glass transition are identified. Complications resulting in symmetric and asymmetric broadening of the glass transition are linked to nanometer...

... Potential-controlled polarization methods can cause large positive shifts of the breakdown potential because of induction effect. The latter gives rise to current hysteresis, which leads to large unpredictable charge densities, which leads to poor accuracy and precision in determining...

... In many applications only the macroscopic effects of eddy currents (those observable at the electrical terminals of an electromagnetic device) are of interest. In these cases eddy currents, hysteresis, and magnetic saturation are readily modeled using coupled electric and magnetic equivalent...

... The potentiokinetic hysteresis technique was utilized to characterize the electrochemical reactions involved in the corrosion of six silver-tin dental amalgams containing approximately 2.0 to 15.0 weight percent copper in a 1.0 percent sodium chloride (NaCl) solution at 23°C over a potential...

.... The hysteresis behavior is explained and related to tensile deformation. Surface studies of highly polished cyclic-bend specimens revealed the fatigue crack nucleation and early growth characteristics. The data are compared to conventional materials, and the fatigue resistance is found to be essentially...

... A hysteresigraph of high accuracy and sensitivity is described. Using galvanometer-photoelectric integrators, this instrument was the first precision recording fluxmeter for tracing accurately and rapidly magnetization curves and hysteresis loops directly on standard rectangular coordinate paper...

... Data for drawing hysteresis curves were originally obtained by the point-by-point method which was tedious and time consuming. For this reason, devices known as hysteresigraphs for drawing hysteresis curves automatically were developed. The first models did not have power to drive a recorder pen...
