Resumen:

The Principle of Natural Proportionality (PNP) postulated in 1985 is a unifying principle from which many general equations used to describe the mechanical behaviour of geomaterials have emerged. This time improved general equations obtained by the PNP were applied to describe the stress-strain and pore pressure behavior for granular soils (sands) tested in undrained triaxial compression tests between confining pressures 50 kPa and 500 kPa. The stress-strain behaviour was fitted using the pre-peak inverted function and the post-peak ductility function. The general equation for pore pressure given by the PNP was also applied to describe the pore pressure behaviour all along the triaxial tests. The different stress-strain and pore pressure parameters that describe the behaviour of granular soils are reported.
