Ever wonder how they worked out #NaturalRubber's molecular structure? how they measure #StrainCrystallization with x-rays? ... well, its the same way they discovered DNA's double helix... https://t.co/8PZPZIZLpF

@zhigangsuo @ShiQingWang4 @CretonCost @JingdaT @ProfZhaoMIT @lin_shaoting @CGRobertson168 Some black filled NRs have Gc > 100 kJ/m^2, w/ G0≈0.05 kJ/m^2. Gc/G0>2000! There is alot of dissipating going on in the crack tip process zone: #viscoelasticity, #straincrystallization, #MullinsEffect. Could rly use FCG rate laws that incorporate process zone behaviors.

Did you know that Endurica's #criticalplaneanalysis is the first and only fatigue theory that predicts non-perpendicular crack development in nonrelaxing tension tests of #naturalrubber with #straincrystallization?

Much of a #tire is #naturalrubber, and #straincrystallization has important effects on tire durability. Use our #fatiguepropertymapping service and our #EnduricaCL / #EnduricaDT fatigue solvers to #getdurabilityright. https://t.co/nuRc04LLtV

Pierre Antoine ALBOUY at #ECCMR19 measured #straincrystallization in #Polychloroprene #CR. Crystallization happens quite rapidly, espeically at high strain (ie at a crack tip)!
