This corresponds to the state shown in “Figure 1-(3) Central Column of the Finite Plate” in https://engineer-education.com/machine-design-70_crack-growth/.
Please enter the values while referring to the figure to ensure accuracy (e.g., whether it is half the crack width or the full crack width).

| Stress Intensity Factor K | N/mm^1.5 |
| Stress Intensity Factor K | MPa·m⁰.⁵ |
K = F × σ × √(πa)
F = sqrt(sec(pi*a/W));
σ: Tensile stress
2a: Total crack length
W: Plate width
K: Stress intensity factor
F: Correction factor
F = sqrt(sec(pi*a/W));
σ: Tensile stress
2a: Total crack length
W: Plate width
K: Stress intensity factor
F: Correction factor
