THEORY OF SOIL PLASTICITY WITH INDEFINITE ANGLE OF NON-COAXIALITY

ONE OF THE TWO DIFFICULTIES THAT HAVE HAMPERED THE DEVELOPMENT OF THE MATHEMATICAL THEORY OF SOIL PLASTICITY WAS RECENTLY OVERCOME BY MANDL AND LUQUE. THEY SHOWED THAT THE NON-COAXIALITY OF THE PRINCIPAL AXES OF A STRESS TENSOR AND A STRAIN-RATE SENSOR CAN OCCUR ONLY DURING THE IN-PLANE DEFORMATION. IT IS DEMONSTRATED IN ONE OF THE EXAMPLES IN THIS PAPER THAT A WELL-KNOWN SOLUTION IN WHICH THE ANGLE OF NON-COAXIALITY IS ASSUMED TO BE ZERO DOES VIOLATE THE ASSUMED BOUNDARY CONDITION. THE THEORY WAS REORGANZIED BY USING NEW INSIGHTS GIVEN BY MANDL AND LUQUE. ANOTHER BREAK-THROUGH IS STILL NEEDED, HOWEVER, TO SYSTEMATIZE A GENERAL METHOD FOR DETERMINING THE ANGLE OF NON-COAXIALITY. /AUTHOR/
