Stress Singularity Analysis of a Cylindrical Bar with a Sharp Notch under Tension and Bending, and Its Application to Fatigue Strength Evaluation.

Simple calculation method for stress concentration and stress intensity of T-shaped member

“…For a stepped structure, the singularity of a Mode I component and the singularity of a Mode II component in s θ are intermingled. However, in the case of ρ-0 the singularity of a Mode I component is dominant [24]. In consideration of the above, in this study, strength evaluation of a corner is performed using the stress intensity factor K I calculated from the stress distribution of s θ .…”
