Laser-based powder bed fusion (LPBF) is a promising additive manufacturing technology, where metallic parts are produced in a layer-wise manner. At each step, a rapid-moving laser irradiates and subsequently melts predefined zones of a relatively thin layer of fine spherical metal ... Per saperne di più
Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... Per saperne di più
Surface plasmons in metal rectangular gratings can form bands and band gaps in their dispersion relations, analogous to those in photonic band-gap crystals and electronic bands in semiconductors. Introducing a dielectric coating atop the metal redshifts the plasmonic band gap, enabling a ... Per saperne di più
Synthetic jet actuators enhance flow control by generating pulsatile jets with zero net mass flux. There is a need to develop a computationally inexpensive model that can generate optimal geometric actuator designs of maximum jet performance. This work investigates the multi-physics ...

Laser additive manufacturing has become an interesting field of engineering which is revolutionizing industrial processes. Selective Laser melting (SLM) is a widely used additive manufacturing technique for 3D printing of metal structures. This process has a particular complexity in ... Per saperne di più
Laser assisted brazing with Al-Si fillers in V-shaped groove configuration is a perspective method for joining of aluminum alloys to titanium. The present work introduces multiscale model that allows estimating diffusion process at titanium/melted zone interface in function of thermal ... Per saperne di più
The formation of porosities in spot laser welding depends on complex thermo-hydraulic phenomena. To understand and control these mechanisms, the COMSOL Multiphysics® software is used to model both the interaction and cooling stages of an isolated impact made with a Nd:YAG pulsed laser. ...

Laser Welded Blank solutions enable to reduce vehicles weight and to optimize their crash performances by means of simultaneous tuning of different grades and thicknesses. The present work aims to characterize numerically and experimentally materials mixing during laser welding. For ... Per saperne di più
Additive manufacturing technology is becoming more popular for the fabrication of metal products as it offers rapid prototyping and large design freedom. However, part quality of components fabricated by current additive manufacturing technology is not comparable to that produced by ... Per saperne di più
A well-collimated intensity profile at long distance has long been a desired laser property crucial for many potential applications. Extending a non-diverging range for ordinary laser beyond kilometers scale would permit superior performance for optical technologies, including LIDAR, or ... Per saperne di più
