Interdisciplinary Research in Viscoelasticity and Rheology
Abstract
A deep understanding of viscoelasticity and rheology is crucial to advanced materials engineering and process design. Examples of such advanced materials are high-strength polymers and additives for lubricants; process design problems include spinning of synthetic fibers and injection molding. The materials involved in these technologies are often highly elastic and very viscous. As a consequence, they often display behavior intermediate between that of a solid and that of a fluid, and their dynamic response involves multiple time-scales. Our goal is to understand the predictions of equations of motion coupled with various constitutive assumptions for advanced, complex materials and to put this knowledge to use in modelling, the design of algorithms, and the computational solution of practical problems. To achieve our goals, our interdisciplinary program has adapted and extended tools in nonlinear analysis of partial differential equations, analytical and computational techniques for hyperbolic conservation laws, and computational techniques from nonlinear structural dynamics.
