Description
Qingshan Jiang and colleagues shrink an ultrasonic hammering process into a single measurable blow. Ultrasonic impact treatment hardens metal surfaces and fights fatigue, but its action flashes by thousands of times a second. Their 2026 paper derives an energy equivalence that swaps the blur for one controlled impact.
A stress-wave model sets the stand-in blow's parameters, and computer simulations mirror both processes. On an aluminum alloy and a common steel, the replica's stress history matched theory within a few percent. Dent depth, residual stress, hardness, and grain patterns all agreed closely too. Engineers gain a bench tool for tuning treatments without chasing kilohertz cycles.
