| Research Abstract |
It was believed impossible that to estimate paleo-stress from elastic rebounded polymineralic material as rock and concretes. The purpose of this study is to develop calcite-twin paleo-piezometer for rock mechanics and safety evaluation of concrete buildings. We succeeded that imaging of inner stress field of polycrystalline aggregates and paleo-piezometric analysis.
