Professor in the Thomas Lord Department of Mechanical Engineering and Materials Science
The second area of interest is to apply recent results from nonlinear dynamical systems theory to problems of practical engineering importance. These include the nonlinear rolling motion of ships leading to capsize; buckling of axially-loaded structural components; aeroelastic flutter of aircraft panels at high supersonic speeds; vibration isolation based on nonlinear springs; energy harvesting; damage detection and structural health monitoring; and the dynamics of very flexible structures including solar sails and marine risers. Professor Virgin conducts mechanical experiments to complement these studies.
The flavor of much of this work is contained in the books:
Introduction to Experimental Nonlinear Dynamics, L.N. Virgin, Cambridge University Press, 2000.
Vibration of Axially Loaded Structures, L.N. Virgin, Cambridge University Press, 2007.
