Outstanding presence of TCAiNMaND researchers at COMPSAFE 2014

Professor Sergio Idelsohn, along with Professor Zhuo Zhuang will deliver two semi-plenary lectures at the forthcoming COMPSAFE2014, the First International Conference on Computational Engineering and Science for Safety and Environmental Problems. COMPSAFE2014 will be held from 13th to 16th of April in Sendai, Japan.

During his lecture Real-Time Computational Fluid Dynamics: a Challenging Demand for Safety and Environmental Problems”, Dr. Idelsohn will depict his work on algorithms to simulate CFD problems as fast as possible, improving the current performance of general-purpose commercial codes, with the aim of changing days of simulations for hours of simulations making feasible the present challenging demand for safety and environmental problems. Dr. Idelsohn will present a pressure-segregation method with an explicit time integrator for the momentum equations without the CFL<1 restriction for stability. This allows large time steps independent of the spatial discretization having equal or better precision that an implicit integration. The method is based on a Lagrangian formulation that may be used with moving or fixed meshes. His lecture will take place on April 14th, Room A+B, at 10.30am.

Dr. Zhuang will focus on how the size effect at submicron scales affects the plasticity of materials. During his lecture ”Dislocation Starvation by Computation/Experiment in Crystal Submicron Pillars”, Dr. Zhuang will present his findings on the research done simulating copper and aluminum single crystal micro pillars. He will elaborate on the mechanical behaviors during the compression process, including dislocation pattern transitions, size-dependent flow stress evolution and strain hardening mechanisms, with special focus on the effect of the free surface interaction and the dislocation junction. His lecture will take place on April 16th, Room B at 10.00am.

The research leading to these results has received funding from the European Community's Seventh Framework Programme, Marie Curie International Research Staff Exchange Scheme (IRSES) under grant agreement n° 612607
