DESCRIPTION:Prof. Dr. Alexander Hartmaier\, Interdisciplinary Center for A
 dvanced Materials Simulation (ICAMS)\, Ruhr-Universität Bochum\, Germany\
 nBio : Dr. Alexander Hartmaier is currently Professor of Materials Science
  (Chair in Micromechanical and Macroscopic Modelling) at Ruhr-Universität
  Bochum/Germany and Director at the Interdisciplinary Centre for Advanced 
 Materials Simulation (ICAMS). Before this appointment he has been Professo
 r of Materials Science at the Friedrich-Alexander-University Erlangen-Nür
 nberg/Germany from November 2005 to May 2008. Prior to this position he he
 aded the group “Nanostructured Materials” in the department “Theory 
 of Mesoscopic Phenomena” of Prof. Huajian Gao at the Max Planck Institut
 e for Metals Research in Stuttgart/Germany. This is the same institute whe
 re he worked on his PhD thesis with the topic “Modeling the brittle-to-d
 uctile transition in tungsten single crystals\,” which he finalized in t
 he year 1999. The thesis has been awarded the Otto-Hahn-Medal of the Max P
 lanck Society. In between his stays at the Max Planck Institute in Stuttga
 rt\, Dr. Hartmaier spent three years in industrial research in responsible
  functions as project leader and group leader. His academic career started
  at the University of Kaiserslautern/Germany\, where he obtained the Diplo
 ma in Physics in 1995 (equivalent to M.Sc.). The focus of his research wor
 k lies on the investigation of deformation and fracture mechanisms of mult
 iphase materials\, mainly with scalebridging modeling and experimental met
 hods.\nAbstract : In order to model the mechanical performance of martensi
 tic steels\, which posses a hierarchical microstructure over several lengt
 h scales\, we need to describe plastic deformation of individual microstru
 ctural constituents\, like laths\, blocks and packets. This is accomplishe
 d by applying crystal plasticity models for single crystalline regions and
  by introducing representative volume elements (RVE) of the rather complex
  microstructures. It will be demonstrated how such RVE-based micromechanic
 al simulations and homogenization methods can be applied to make predictio
 ns on macroscopic mechanical properties of tempered martensitic steels. Fu
 rthermore\, it will be discussed how the relatively large number of input 
 parameters that is needed for such micromechanical modeling can be obtaine
 d either by atomistic simulations or by sophisticated micromechanical expe
 riments.
