Dietmar Grossreceived his Engineering Diploma in Applied Mechanics and his Doctor of Engineering degree at the University of Rostock. He was Research Associate at the University of Stuttgart and since 1976 he is Professor of Mechanics at the University of Darmstadt. His research interests are mainly focused on modern solid mechanics on the macro and micro scale, including advanced materials. Werner Haugerstudied Applied Mathematics and Mechanics at the University of Karlsruhe and received his Ph.D. in Theoretical and Applied Mechanics from Northwestern University in Evanston. He worked in industry for several years, was a Professor at the Helmut-Schmidt-University in Hamburg and went to the…
