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
Irradiation of various surface materials by ultra-short laser radiation, typically with pulse widths of 10-300 fs, results in the development of Laser-induced self-organized periodic surface structures (ripples). The periodicity of these structures ranges from the wavelength <em>λ ... 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
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
Time-dependent multiphysical simulation of pulsed and continuous laser welding of dissimilar metals, based on Moving Mesh (ALE) approach, is proposed. Strong coupling between heat transfer, laminar compressible flow and ALE is used. The model was validated for a case of single ... Per saperne di più
Additive manufacturing gathers technologies where near net shape components are produced by depositing successive layers of materials. Among these technologies, the Layer Beam Melting (LBM) process – often referred to as Selective Laser Melting (SLM) – is garnering industrial interest, ... Per saperne di più
We present here the development of an optical human eye model – based on Ray Optics module in order to reproduce the eye optical properties. Current simulations in literature do not fully cover the light propagation inside all parts of the eye by taking into account the absorption but ... Per saperne di più
