摘要
Based on the experimental results in the full stress-strain process of sandstone, siltstone, mudstone,coal, marble by using the advanced experimental equipmeut. This paper studies the characteristics of volumetric strain in the full stress-strain process. The results give out some new knowledge and conclusions and are helpful to the study on rock mechanical properties, constitutive law and strength theory.
