Abstract : One of the difficulties that have hampered the development of the mathematical theory of soil plasticity was recently overcome by Mandl and Luque. They showed that the noncoaxiality of the principal axes of a stress tensor and a strainrate tensor can occur only in plane deformation. Their assumption that the angle of noncoaxiality should be a material constant cannot be supported, however, The angle of noncoaxiality should be determined so that the solution to the given problem can exist. It is demonstrated in one of the examples in the report that a wellknown solution in which the angle of noncoaxiality is assumed to be zero does violate the assumed boundary condition. The theory was reorganized by using new insights given by Mandl and Luque. It is concluded that still missing is one condition that enables us to determine the angle of noncoaxiality as a function of space. (Author)
