✦ Synopsis

The effect of an external stress on the barrier properties of natural, bromobutyl, and nitrile rubber were studied using a modified ASTM permeation method. Stress-induced changes such as a decrease in the breakthrough time with mechanical elongation was observed. Upon application of a small mechanical deformation, little change was observed in terms of steady-state permeation flux. On the other hand, a stress-enhanced diffusion was observed for most of the solvent/rubber pairs studied.

The effects of shrink fitting on the magnetic properties of iron cores are investigated in order to simulate the magnetic behavior of iron cores mounted in motor frames. Shrink fittings, of course, decrease permeability and increase effective magnetostriction and magnetic loss. It is well known that
