Laser beam shaping offers remarkable possibilities to control and optimise process stability tailor material properties structure in laser-based welding additive manufacturing. However, little is known about the influence of laser on complex melt-pool behaviour, solidified melt-track bead profile microstructural grain morphology processing. A simulation-based approach utilised present work study effects intensity angle incidence behaviour conduction-mode melting stainless steel 316L plates....
Modeling the thermal and fluid flow fields in laser-based directed energy deposition (DED-LB) is crucial for understanding process behavior ensuring part quality. However, existing models often fail to accurately predict these due simplifying assumptions, particularly regarding powder particle-induced attenuation laser power density distribution, variable material properties parameters. The present work introduces a high-fidelity multi-phase thermal-fluid model driven by combination of...
Shape memory alloys (SMA) are nowadays widely used in different industries. The two extraordinary behaviors of superelasticity and shape effect make these a super wear-resistant material. In range SMA applications, contact between adjacent surfaces occurs. this research, formerly-developed model, which individually considers each asperity, is extended to cases where superelastic used. Since constitutive equations SMAs based on stress strain, establish relationship classical models the main...
