    In true triaxial apparatus, samples of soil are subjected to three independent principal stresses and strains. Such apparatus can readily be used for controlled exploration of principal stress or principal strain space to provide information concerning the anisotropic response of the soil to aid the development of constitutive relations.

    The Cambridge true triaxial apparatus has recently been reconstructed and is described in its new form. Some experimental data from a stress controlled test on kaolin are presented as an illustration of the capabilities of the apparatus and as an illustration of alternative ways in which such data may be presented while maintaining maximum objectivity.
