This document presents information on the bending of single-notched bars. It discusses: 1. The bending behavior depends on the notch angle ψ - for ψ<32.7°, the sliplines are straight meeting the surface at 45° forming a fan shape. For ψ>32.7°, the sliplines are curved circular arcs connecting the stress-free surfaces. 2. Equations are provided to calculate the yield moment, constraint factor, slipline geometry parameters like radii and heights based on the notch angle ψ. 3. A table shows the calculated geometrical parameters and constraint factors for different notch angles ψ.
