چکیده انگلیسی
The results show that the earing profile is mainly dictated by the compression r-values in-plane directionalities, which are commonly unavailable for thin metallic sheets. The adoption of the CPB06 taking into account the tension-compression asymmetry, with an associated flow rule, enables the simultaneous prediction of both compression yield stress and r-values directionalities. The compression yield stresses directionalities seem to play a major role in the thickness prediction. Therefore, it is recommended the use of a yield criterion that is flexible enough to describe both the yield stresses and r-values directionalities, including the ones in compression, even for materials that present a small SD effect.
