We respond to the technical content of the discussion as follows:

    Discussant appears to have erroneously assumed that differences in material response under tensile (here J1 −ve) and compressive (J1 +ve) regimes necessitate different parameters and that use of a single set of parameters implies identical responses under these regimes. The yield function we presented is not entirely symmetric about the J2D axis. A single set of parameters can handle different material responses, as also different ultimate stresses, for tensile and for compressive stress paths. We are unsure why discussant wants yield surface discontinuity between compressive and tensile regimes. Von Mises surfaces span both tensile and compressive regions without breaks at J1 = 0. When loading solder in shear along the J2D axis with J1 nominally zero, we do not expect vanishingly small perturbations...
