  1. Stress and Texture Investigations by Means of Neutron Diffraction Opening Remarks Ove Stephansson Seismic Hazard and Stress Field GFZ German Research Centre for Geosciences Potsdam

  2. Characterization of an Area, Site for a Rock Engineering Project Produce a 3-D model of the site and target area • Topography • Soil cover • Rock mass lithology • Structural geology • Hydrogeology • Geochemistry • Thermal properties • Rock mechanics • Rock stress

  3. Methodology for Development of the Final Rock Stress Model – FRSM of a Site and an Area After Zang & Stephansson 2010

  4. World Stress Map of Europe, Edition 2008 http://dc-app3-14.gfz-potsdam.de/ After World Stress Map (2008)

  5. Stress Decoupling in Eastern Part of North German Basin After Zang & Stephansson 2010

  6. Methodology for Development of the Final Rock Stress Model – FRSM of a Site and an Area After Zang & Stephansson 2010

  7. Hydraulic fracturing equipment of type Mesey Courtesy by F Rummel

  8. Numerical stress modelling with distinct element code 3DEC for deep geological disposal of spent nuclear fuel at Forsmark, Sweden

  9. Angle-dispersive Neutron Diffraction

  10. Problems in Rock Stress Measurements where Neutron Diffraction can Contribute • Rock anisotropy • Heterogeneity • Discontinuities e.g. microcracks • Residual stresses • Paleostresses • Kaiser effect • Volume effects • Influence of fluids
