Abstract

An initially isotropic and undamaged quartzite was submitted to spherical divergent shock-wave experiments. Macroscopic and microscopic examination of the recovered samples enabled compaction and fracturation to be quantified. The ARMOR behaviour model was adjusted using a series of triaxial tests and plate impact tests. The model thus defined was used to reproduce the spherical divergent tests macroscopically. This work provides a database on a quartzite which can contribute to understanding the rheology of rocks subjected to high pressures and to improving the behaviour modelling. 1 Introduction The aim of this study is to investigate the rheology of a rock submitted to
