Stress softening in natural rubber vulcanizates. Part II. Stress softening effects in pure gum and filler loaded rubbers
Abstract Considerable stress softening (Mullins effect) occurs in both gum and filler loaded vulcanizates of natural rubber and SBR. When compared at the same stress, the extent of softening is similar in both gum and filled vulcanizates. The stress softening is shown to be mainly due to changes in the rubber phase in…
Stress softening in rubber vulcanizates. Part I. Use of a strain amplification factor to describe the elastic behavior of filler‐reinforced vulcanized rubber
Abstract Measurements of Young's modulus of vulcanized rubbers containing thermal carbon black show the predicted dependence on the volume concentration given by relationships derived for a suspension of spherical particles, for example, that due to Guth, Simha, and Gold which gives E = E 0 (1 + 2.5 c + 14.1 c 2 ).

Electron scattering on magnetic impurities in metals and anomalous resistivity effects
A special quantum field theory technique for a system of spins was used to evaluate the resistivity of metals containing paramagnetic impurities, assuming $J/{\mathrm{\ensuremath{\epsilon}}}_{F}\ensuremath{\ll}\mathit{1}$, for an arbitrary value of ($J/{\mathrm{\ensuremath{\epsilon}}}_{F}$) ln (${\mathrm{\ensuremath{\…
