triaxial test


Test results showed the internal friction angle is different from zero. If anyone has a paper about triaxial test failure conditions in clay, could share?

This could easily happen in a clay if the clay is not fully saturated. Remember phi is equal to zero because, the increment of pressure goes into pore pressure, but if you are not fully saturated this will not happen.
