Professor
Cornelius Horgan in
Science
Cornelius O. Horgan, Wills Johnson Professor of Applied Mathematics and Mechanics in the Department of Civil and Environmental Engineering was a Visiting Professor at Dublin City University
(DCU) , Dublin, Ireland in June 2007. Professor Horgan delivered a series of lectures on the development and application of new constitutive models for rubber-like and biological materials that reflect rapid strain-stiffening at large strains. Horgan collaborates actively with colleagues at DCU on large deformations of rubber with recent emphasis on the effects of small compressibility. The results are particularly relevant to the accurate implementation of commercial finite element codes where the usual assumption of incompressibility leads to element locking and small compressibility is artificially introduced. Professor Horgan was also quoted in the August 31, 2007 issue of “Science” regarding work of other colleagues in Italy and France on an application of nonlinear elasticity theory to the problem of tension and torsion of a rubber-like solid cylinder. Due to nonlinearity, the combined loading is more efficient than each applied sequentially. That is why it is easier to extract a cork from a wine bottle when pulling is accompanied by twisting !
