| Abstract: | A set of complete stree-strain experiments of marble and sandstone were performed under pressure and temperature. The influences of pressure and temperature on ultimate strength,residual strength,elastic modulus,rupture angles and compressional velocities were examined. The features of modulus and velocities pre-and post-failure were also studied and some simple analysis were given. |
