Application of Non-Linear Notch Mechanics to Biaxial Stress Problems

Abstract:

In this study, it was made clear that the non-linear notch mechanics is useful not only in the case of uniaxial tension but also in the case of biaxial tension. The difference of both cases is as follows. In the former the plastic strain field near a notch root is determined by εp y0,FEM (plastic strain at a notch root) and ρ (notch root radius) alone, but in the latter case it is determined by εp y0,FEM, ρ and stress ratio k=σxn/σyn.
