Arc welding is a widely used process in heavy industry for the assembly of metallic components. To ensure high-quality welds, it is essential to understand both the welding process and the complex interactions within the melt pool. Numerical simulation is employed as a predictive tool to ... 詳細を見る
Quasi-static 2D-MEMS vector scanners are micro-opto-electro-mechanical systems (MOEMS) made of monocrystalline silicon. The primary application for these controllable micromirrors is the high dynamic and precise deflection of laser beams, for example in light detection and ranging ... 詳細を見る
The process-induced deformation in the DED fabricated part is a critical issue to the scaling of the technology. Currently, an inefficient and expensive experiment trial-and-error approach is utilized to tackle this issue, however it is not feasible for large parts. Researchers have ... 詳細を見る
A Laser-welded blank (LWB) consists of steels of different thicknesses and/or grades welded together to produce a single blank prior to the forming process. LWB are mostly used in the automotive field where the high productivity of the laser welding process is an advantage. Numerical ... 詳細を見る
The article deals with the magnetically-supported high-power full-penetration laser beam welding of aluminum. A stationary simulation was conducted accounting for the effects of natural convection, Marangoni convection and solid-liquid phase transition as well as an electromagnetic ... 詳細を見る
This study presents a numerical investigation of optical butt-coupling between Vertical-Cavity Surface-Emitting Lasers (VCSELs) operating at 850 nm and Standard Single-Mode Fiber (SSMF), a widely adopted configuration in cost-effective, high-speed optical interconnects, especially in ... 詳細を見る
A 2D axisymmetric model was considered in order to evaluate the propagation paths of the ultrasonic waves generated inside an aluminum plate sample due to a rapid thermal expansion produced by laser pulse. Laser Doppler Vibrometer is used to experimentally validate the numerical results ... 詳細を見る
During the welding of tantalum with a ND: YAG pulsed laser, a deep and narrow cavity, called the keyhole, is formed. At the end of the process, surface tension forces provoke the collapse of the keyhole. For important interface deformations, gas bubbles can be trapped into the melting ... 詳細を見る
The Dynamic Transmission Electron Microscope (DTEM) at Lawrence Livermore National Laboratory is a unique instrument able to capture images of fast-evolving microstructure with exposure times of only 15 ns. This is more than six orders of magnitude faster than conventional in situ ... 詳細を見る
Simulation of laser pulse-train (25ns, 60 kHz and 3000 pulses) heating Sol-Gel thin film using COMSOL Multiphysics software is investigated. The results show two kinds of temperatures formed on film surface by laser pulse-train heating. One is a single pulse induced transient peak ... 詳細を見る
