A C-U triaxial test was conducted on a sand sample. At the failure moment, the confining pressure was 400 kPa. Determine the following • The friction angle o in term of total stress • The friction angle d' in term of effective stress • The angle of the failure plane formed with the major principal stress plane The effective normal and shear stresses on the failure plane (o'n, o'n) • Skempton's pore pressure factor at failure, A .
