AEM Seminar Series: Dr. Olesya I. Zhupanska
Dr. Olesya I. Zhupanska, an Associate Professor of Mechanical Engineering and Applied Mathematics and Computational Sciences and Robert and Virginia Wheeler Faculty Fellow of Engineering at the University of Iowa, will be speaking as part of the Aerospace Engineering and Mechanic’s Research Seminar Series on “Electro-Magneto-Mechanical Coupling in Anisotropic Electrically Conductive Composites”.
In this talk, dynamic processes occurring in electrically conductive anisotropic (i.e. carbon fiber polymer matrix) composites as a result of application of electromagnetic and mechanical loads will be discussed. Theoretical analysis is based on the theory of magneto-thermo-elasticity. Fiberreinforced composite materials are essentially anisotropic not only in their mechanical, but also in the electrical properties. Electrical permittivity and conductivity are represented by the tensors of the second order, and the Lorentz force depends not only on the electric and magnetic fields strength and orientation, but also on the velocity and the rate of deformation of the solid, which makes the system of the governing equations coupled and essentially nonlinear. Physics-based hypotheses and dimension reduction solution procedures for these nonlinear systems will be presented. PDE-constrained optimization approach for active control of the mechanical response via an electromagnetic field will be introduced and numerical solution methods for the deterministic and two-stage stochastic PDE-constrained optimization problems will be discussed. The developed models and solution methods are applied to the problems of the dynamic response of carbon fiber polymer matrix composite plates subjected to transverse deterministic and stochastic mechanical loads and various electromagnetic fields (including DC, AC, and pulsed electric current and constant magnetic field). The numerical results showing interacting effects of the mechanical and electromagnetic loads will be discussed.
