Rubber has unique physical and chemical properties. The stress-strain behavior of rubber exhibits the Mullins and Payne effects and is often modeled as hyperelastic. The rubber strain crystallizes. Natural rubber is sensitive to vulcanization and susceptible to ozone cracking due to the weak allyl C
