The answer is no. Sanford remains relevant because FEA is garbage-in-garbage-out. Modern software outputs beautiful colored stress contours, but these contours are mesh-dependent. Sanford teaches the singularity element—specifically, how to use the quarter-point element (Barsoom’s method). Without understanding Chapter 5 of Sanford, a young engineer will trust an FEA result that might be off by 50%. Finding a direct PDF of " Principles of

Principles of Fracture Mechanics by R.J. Sanford is a foundational text in mechanical engineering that bridges the gap between theoretical elasticity and practical engineering design. First published in 2003, it has become a standard resource for graduate-level courses and professional engineers seeking to understand how and why materials fail.
