YIELDING OF SAND IN PLANE STRAIN

The discusser points out that the equation proposed by the author to quantify a lack of normality in the plastic strain increment vector to the yield surface, utilizes a flow rule which appears to be the same as one used by Schofield and Wroth. The difference lies not in the choice of flow rule but rather in the choice of yield function. The yield function is obtained by Schofield and Wroth by requiring the sand to satisfy Druker's stability criterion. In the flow rule discussed by the author, the related plastic potential function is yet to be established unequivocally. The author implies that no such plastic potential function is possible.
