CLOSURE ON SETTLEMENT OF STRIP LOAD ON ELASTIC-PLASTIC SOIL

THE WRITERS AGREE WITH HANSEN THAT THEIR RESULTS DO AGREE MORE WITH PRANDTL'S SOLUTION THAN WITH HILL'S. THE PURPOSE IN MENTIONING HILL'S WAS TO POINT OUT THAT THE LIMIT SOLUTION IS UNIQUE ONLY WITH RESPECT TO LOADS AT FAILURE, AND NOT WITH RESPECT TO THE EXACT MODE OF FAILURE. THE DISCRETIZATION INVOLVED IN ANY FINITE NUMERICAL PROCEDURE CAN CERTAINLY MODIFY THE RESULTS, ESPECIALLY AT SINGULARITIES. VILLIAPPAN'S RESULTS WERE DERIVED FOR A VERY DIFFERENT YIELD CRITERION FROM THAT USED BY THE WRITERS, BUT IT IS ENCOURAGING TO OBSERVE SOME QUALITATIVE AGREEMENT. THE WRITERS' METHOD IS ESSENTIALLY THAT OF CHANGING THE STIFFNESS MATRIX AT EACH STEP OF LOAD AND ITERATING UNTIL THE CALCULATED STRESSES ARE CORRECTLY BACK ON THE YIELD SURFACE. CORRECTIONS ARE GIVEN FOR AN EQUATION IN THE ORIGINAL PAPER. REFERENCES: SETTLEMENT OF STRIP LOAD ON ELASTIC-PLASTIC SOIL, KAARE HOEG, JOHN T. CHRISTIAN, ROBERT V.
