Mullins effect tear strength
WebThe effect of fiber length on paper strength has been studied extensively. The results, concerning for example the tensile index, vary a lot. Some results show that the tensile index of paper increases with fiber length and some studies show the opposite results. In most cases the discrepancies can be explained by the distinctive ways of fiber ...

WebLoading–unloading cycles showed a strong stress-softening (Mullins) effect, especially at 8.3 wt.% nanotubes ( Fig. 12.19B ), which is hardly explained by a hydrodynamical model [256], which could be related to some degree to CNT alignment occurring in … The Mullins effect is a particular aspect of the mechanical response in filled rubbers, in which the stress–strain curve depends on the maximum loading previously encountered. The phenomenon, named for rubber scientist Leonard Mullins, working at the Tun Abdul Razak Research Centre in Hertford, can be idealized for many purposes as an instantaneous and irreversible softening of the stress–strain curve that occurs whenever the load increases beyond its prior all-time maxim…
