Oozing characteristics in screw extrusion additive manufacturing

Abstract Additive Manufacturing (AM) is a non-conventional manufacturing process that enables the physical realization of components through layer-by-layer material deposition. Among the different AM techniques, Screw Extrusion Additive Manufacturing (SEAM) uses an extruder screw...

Inverse-Problem Approach for 3MA Electromagnetic NDT on Laser-Hardened Materials

This work presents a numerical framework for the electromagnetic modeling and inverse characterization of laser-hardened steels using 3MA (Micromagnetic Multiparameter Microstructure and Stress Analysis) non-destructive testing. The proposed methodology combines a simplified two-...
