The following figure shows a general yield locus on -plane. Let's define Lode 20-03-0 -3 tane, 0 0 03. parameter u such that = 03-01 (1) Derive the above equation. (2) Show that = 0 represent a state of pure shear, and = -1 represent = a state of uniaxial compression (note: might add hydrostatic components). (3) Show that, for isotropic materials without Bauschinger effect, the mid lines (dash lines in the figure) of any two principal stress axes are symmetrical lines of yield locus. 02 03 -0 TO -03 P(q,q,g) 01 The following figure shows a general yield locus on -plane.
