Elastic-Plastic Stress Singularity Near the Tip of V-Notch

摘要

In the present study, the plastic stress singularity occurring in a V-notch is studied. A practical method is introduced to solve homogeneous differential equations obtained in the analysis. The results so obtained appear to be quite satisfactory. Based on the numerical results, the effects of the notch geometry and the hardening power on the singularity are discussed. In particular, an approximate expression is presented for the evaluation of the plastic stress singularity.
