BS 7910 SIF (Annex M)

BS 7910:2019 Annex M — Analytical SIF solutions for 34 crack geometries

BS 7910 Annex M — Analytical Stress Intensity Factor (K_I)

Based on BS 7910:2019+A1:2020 Annex M, this module provides comprehensive analytical solutions for Stress Intensity Factors (SIF):

• Double Front Points: Simultaneously solves and compares SIF values for the deepest point (Point A) and the surface point (Point C) for 3D flaws like semi-elliptical cracks.
• 8 Physical Geometry Groups (34 Cases): Covers flat plate Newman-Raju solutions, Folias bulging factors for shells, James & Mills round bar edge cracks, UNF/ISO bolt thread root cracks, and Maddox weld toe/root models.
• High-order Polynomial Fits & Nuclear-grade Corrections: Supports 0 to 5th-order non-linear stress polynomial coefficients, and provides precise magnification corrections for misalignment (k_m), macroscopic stress concentrations (k_{tm}/k_{tb}), and local weld toe geometry (M_{km}/M_{kb}).
