David Kammer joined Cornell's School of Civil and Environmental Engineering in January 2016. He received his B.Sc. and M.Sc. in Civil Engineering from the Swiss Federal Institute of Technology in Lausanne (EPFL). During his studies, he was an exchange student in CEE at Carnegie Mellon University in 2007-2008, a volunteer project manager for a development project in Senegal in 2009, and an executive vice director of a non-governmental organization supporting sustainable cities. In 2014, he completed his Ph.D. in Mechanics at EPFL. His graduate research focused on the use of numerical models to gain fundamental insights on the propagation of slip fronts at frictional interfaces. He then worked as a research scientist at Bern University of Applied Sciences and as a postdoctoral fellow at the Hebrew University of Jerusalem
David is interested in the mechanics of dynamic and transient phenomena leading to failure of materials and structures. His research is focused on the effects that small- and meso-scale properties have on the overall response of solids and structures with particular interest in heterogeneous materials and interfaces. He develops modern numerical models and applies high-performance computing to obtain high-resolution simulations of physical phenomena occurring in failure mechanisms. His approach combines computational mechanics with simple but insightful theoretical models from applied mechanics. Specific research topics include the characterization of slip fronts propagating at sub-Rayleigh or super-shear speeds during stick-slip mechanism, the stability analysis of frictional sliding along bimaterial interfaces, the scale-effect quantification of interface heterogeneities on rupture dynamics, the determination of meso-scale interface weakening processes using macro-to-micro as well as micro-to-macro modeling strategies, and the development of predictive models for failure of heterogeneous materials under multi-physical loading conditions.Research Group Members
Kammer's teaching focus is on computational mechanics, as well as on solid and structural mechanics.
