DESCRIPTION:Helena Van Swygenhoven\, EPFL IMX\, Paul Scherrer Institute\, 
 Villigen\nBio : Helena Van Swygenhoven is Professor in IMX/STI/EPFL and a 
 senior research staff member and group leader at the Paul Scherrer Institu
 te\, Switzerland. She studied physics in the Free University of Brussels a
 nd received her PhD degree in physics from the Central Jury in Belgium on 
 radiation damage in materials.\nAfter a professional break for motherhood\
 , she joined the Fusion Technology Division at the Paul Scherrer Institute
  with a Marie-Heim Vögtlin stipendium from the Swiss National Science Fou
 ndation. She moved to the Neutron Spallation Source department and started
  a research group focusing on the mechanical bahaviour of metallic microst
 ructures. The group is internationally known for the development of synerg
 ies between computational material science and in-situ experiments with Xr
 ays and neutrons.\nAbstract : The microstructure of today’s metals is st
 eadily increasing in complexity because of the increasing demands in perfo
 rmance. To develop improved predictive computational models one needs char
 acterization and testing methods that can follow the dynamics of these mic
 rostructures to validate computational models and/or can provide input par
 ameters for new models.\nRecent advances in X-ray and neutron technologies
  at large facilities have brought increased beam intensities\, improved de
 tector efficiencies and sub-micron focusing techniques. In-situ mechanical
  testing during X-ray and neutron diffraction has become an excellent rese
 arch method to follow the dynamics of microstructures under load. In-situ 
 experiments provide information on elastic and plastic anisotropy\, load-s
 haring\, strengthening and phase transforming mechanisms\, or degradation 
 phenomena. These methods are therefore excellent tools to develop synergie
 s with computational modeling.\nIn this seminar the basics of insitu mecha
 nical testing will be explained and illustrated with research performed at
  the Swiss Light Source (SLS) and the Swiss Neutron Spallation source (SIN
 Q) at the Paul Scherrer Institute.
