Solid or liquid?

On March 3rd, 2023, Postdoc Rob Wagner and Ph.D. candidate Zhongtong Wang, in conjunction with the Cornell Center for Materials Research, attended Dryden Elementary School to teach 3rd-grade students about the phases of matter, and viscoelastic materials. In this interactive lesson designed by Rob, Rob and Zhongtong used hands-on demonstrations spanning from rubber bands and maple […]

Paper on modeling elastomers with ionic bonds and entanglements out in Mechanics of Materials

Dynamic crosslinks and entanglements play a significant role in tuning mechanical properties of elastomers and gels. In our recent paper in the journal of Mechanics of Materials, we report a continuum modeling framework that considers these two mechanisms for adding toughness and strength to polymers – ionic bonding and entanglements. This theoretical study led by Zhongtong Wang […]
