THREE-DIMENSIONAL YIELD CRITERION OF C-PHI MATERIAL.
Abstract
A general three-dimensional yield criterion of an ideal soil, called c-phi material, is determined that can coincide with the Shield yield criterion and the Drucker-Prager yield criterion by giving appropriate values to the parameters contained. When expressed on an octahedral plane in the principal-stress space, the yield criterion is represented by a hexagon of curved sides formed of conic sections. The geometric relationships satisfied by a family of curved hexagons are investigated. (Author)
