The mechanics of plastic energy dissipation for a stably growing crack in a finite-thickness plate under biaxial loading is investigated by approximate analysis. It is shown that plastic energy dissipation rate increases with the biaxial stress ratio more rapidly on the negative side than on the positive side. The increase becomes larger with greater values of the applied stress normal to the crack. For plane stress conditions, the minimum value of plastic energy dissipation rate occurs when the biaxial stress ratio is unity, while for plane strain conditions, the minimum rate corresponds to the biaxial stress ratio between 2 and 3.
