Incremental plasticity relations are frequently defined in terms of stress invariants and their related strain quantities , and in computation need to be transformed to a Cartesian co-ordinate system . This paper indicates how much transformation can be implemented simply and consistently without redefining yield and plastic potential. Indeed, the procedure developed is applicable to the transformation between any two stress spaces.
