RISImprovement of a Cycle J Integral for CT Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The cycle J integral formula for CT specimens has been improved as follows: ΔJ=(2/Bb)(α1 •U + α2 •ΔP•Δδ) + (2/Bb)Ue −1.2025a/w + 0.6233 for 0.3≤a/w≤0.53; ΔJ=(2/Bb)(α1 •U + α2 •ΔP•Δδ) + (2/Bb)Ue ...
