By 2027, most heavy haul railroads and aviation MROs (Maintenance, Repair, and Overhaul) will likely mandate reporting for all critical life-limited parts.
The defining characteristic of NFG-Multi-Crack is the interaction between adjacent crack tips. When two parallel cracks grow near each other, their stress fields overlap. This phenomenon, known as stress shielding or stress amplification , can either stall the growth of one crack or violently accelerate the growth of another. nfg-multi-crack
Acoustic Emission is currently the gold standard for detecting active multi-crack growth. As a crack propagates, it releases energy in the form of stress waves. In an NFG environment, sensors can triangulate the By 2027, most heavy haul railroads and aviation
