SUMMARY:PICS Colloquium: "Mechanics of Polymeric Gels"
DESCRIPTION:This talk discusses recent and ongoing research on the multiphysics response of polymeric gels. A polymeric gel is a polymeric material swollen by a fluid\, and the intake or out-flow causes large deformations. Also\, many gels respond to environmental stimuli such as temperature\, electric and magnetic fields\, pH\, and more. The responsiveness of polymeric gels to environmental stimuli has been widely employed in soft robotics\, and the poten-tial applications of soft robots are vast. The fast emerging development of gel-based soft robots makes understanding the mechanics of this class of material an important task for simulating their operation. \n\nThe talk begins with recent experimental observations on the mechanical behavior of polymeric gels. Then a continuum level model for the coupled deformation-diffusion re- sponse of gels that incorporates anisotropy and inelasticity is summarized. That is followed by model calibration and attempts for validation on relatively simple gels. Numerical sim-ulations are performed to show the behavior of the model\, and qualitative comparisons are made to experiments of a soft robotic gripper. Results show that the behavior of polymeric gels is even more dependent on fluid uptake than previously thought.
