N2 - Many structures damaged in recent earthquakes had cracks from welds that broke the Hauges of beams, broke llanges from columns, or veered of f, sometimes through columns. At least some structures were fully plastic during crack growth.. A complete asymmetric, plane strain, non-hardening, isotropic, rigid-plastic fracture mechanics is developed to predict such asymmetric crack growth from small specimen tests. For short cantilever specimens with an EDM slot across from an of fset shoulder, slip line fields give the three crack tip driving parameters; a slip direction 58" to 77" from the transverse (loading) direction, a moderate mean normal stress, and a slip of about half the applied displacement. Tests on A710 steel, TS = 630 MPa, gave the crack tip growth responses at that mean normal stress; cracking within 4" of the observed slip direction and growth per unit slip of 3 to 5, somewhat low compared to other configurations and materials.
