Elasticity, Continuum Mechanics, Calculus of Variations
My research lies in the areas of continuum mechanics, the calculus of variations and partial differential equations. I am especially interested in the nonlinear theory of elasticity. In recent years I have concentrated on analyzing some mathematical models for the formation of holes in rubbery polymers. Experiments on such elastomers reveal that a major failure mechanism is that of cavity formation and coalescence; when loads are applied small holes appear, grow, and combine to form cracks. A similar material failure can also occur in glass; in certain optical fibers low levels of laser light together with moderate heat will cause a series of cavities to cascade down the core of the fiber, seriously degrading its optical properties. The analysis of such material failures has lead to new and interesting questions concerning: the existence of, and admissibility criterion for, singular solutions to hyperbolic systems of partial differential equations; the existence of singular solutions to certain parabolic systems of partial differential equations; the existence of minimizers with singularities for problems in the calculus of variations; and the regularity and fine properties of singular minimizers.
