Computational Modelling of Problems of Viscoelasticity

10:30 AM-12:30 PM

As advanced engineering applications require more sophisticated damping mechanisms, it is becoming necessary to develop similarly sophisticated theoretical and numerical simulation techniques for the viscoelastic materials used for the damping. The speakers will address research broadly focused on: adaptive finite element modelling using both hereditary integral and internal variable constitutive models, and nonlinear hysteritic models for filled elastomers. It is anticipated that the presentations will interest engineers working on damping, as well as mathematicians working on numerical viscoelasticity.
