Effects of Different Absorption Models in the Damage Dimensions for High-Power Laser Irradiation of CFRP: Numerical Modeling and Experimental Validation
Springer Science and Business Media LLC - - Trang 1-23 - 2024
Dipten Misra, Souren Mitra, Hori Lol Meena, Saumendra Nath Datta, Jagannath Nayak, Paramasivan K., Souradip Paul
In the present study, the effects of three modes of reflection, namely, single reflection, multiple reflection and trapped reflection between the carbon fibers, on the removal of carbon fiber reinforced polymer (CFRP) is studied. Towards this, a finite element based numerical simulation methodology is established incorporating the chain of phenomena that occur in a CFRP panel, namely, polymer cros...... hiện toàn bộ
Laser-Based Directed Energy Deposition (L-DED) Processing of Water Atomized 42CrMo4 Powder
Springer Science and Business Media LLC - Tập 10 - Trang 32-63 - 2022
G. A. W. Sweet, I. W. Donaldson, C. T. Schade, D. P. Bishop
This study investigates the viability of utilizing a low-cost steel feedstock powder in the context of laser-based directed energy deposition (DED) processing. Here, water atomized 42CrMo4 (comparable to 4140) ferrous powder was deposited on a AISI 4140 substrate using an Optomec MTS 500-AM controlled atmosphere DED system. A statistical design of experiments (DOE) approach was used to parametrica...... hiện toàn bộ
Monitoring Opportunities in Fiber Laser Flame Cutting
Springer Science and Business Media LLC - Tập 8 - Trang 491-510 - 2021
Nikita Levichev, Alberto Tomás García, Joost R. Duflou
Triggered by smart and zero-defect manufacturing paradigms, in situ quality assurance has become an emerging necessity for industrial laser cutting. Within this work, several real-time monitoring concepts have been tested for 4 kW Ytterbium fiber laser flame cutting of 15 mm mild steel plates. Cut quality deteriorations caused by cutting at varying speeds as well as by the preheating effect are ex...... hiện toàn bộ
Experimental Investigation on the Effect of Nickel-plating Thickness on Continuous-wave Laser Welding of Copper and Steel Tab Joints for Battery Manufacturing
Springer Science and Business Media LLC - - Trang 1-18 - 2024
Michele Francioso, Caterina Angeloni, Alessandro Fortunato, Erica Liverani, Alessandro Ascari
The welding of dissimilar materials, such as copper and steel, holds significant industrial significance in the production of electric vehicle batteries. These materials are commonly used in the case of connections between busbars and cylindrical cells inside a battery pack. To optimize welding and guarantee protection against corrosion, nickel is commonly used in the form of a coating. In this pa...... hiện toàn bộ

Md. Nazrul Islam, Atanu Kumar Das, Md Morsaline Billah, Khandkar-Siddikur Rahman, Salim Hiziroglu, Nobuaki Hattori, David A. Agar, Magnus Rudolfsson
Wood is one of the most valuable and abundant renewable materials. Development of wood-based advanced products comprises an important and exciting area of research. In recent times, replacement of traditional technology for the improvement of wood preservation and drying has drawn substantial scientific interest. These technologies are important for improving the functional properties of wood. Mor...... hiện toàn bộ
Laser Sintering of Abrasive Layers with Inclusions of Cubic Boron Nitride Grains
Springer Science and Business Media LLC - Tập 5 - Trang 298-316 - 2018
Olexiy Goncharuk, Ruslan Zhuk, Olexiy Kaglyak, Vitaliy Dzhemelinskyi, Dmytro Lesyk
One of the mainstream technologies for industrial tools manufacturing is the high-speed local heating technique that drastically increases the productivity of tools manufacturing. With further optimization of sintering processes, it is possible to manufacture industrial processing tools with high density and relatively small grain size. The use of a focused laser beam as a heating source also cont...... hiện toàn bộ
Influence of Operating Parameters on CO2 Laser Welded Butt Joints of AISI 304 Stainless Steel Thin Sheets
Springer Science and Business Media LLC - Tập 6 - Trang 205-227 - 2019
Pardeep Pankaj, Avinish Tiwari, Pankaj Biswas
In this work, experimental studies were carried out to join the thin AISI 304 stainless steel sheets thickness of 1 mm using CO2 laser. The effect of welding process parameters (i.e. laser power and welding speed) with varying stand-off distance on mechanical properties, temperature distribution and weld induced residual deformation were determined. The microstructures of the fusion zone, heat aff...... hiện toàn bộ
Efficient Yet Accessible Arduino-based Control System for Laser Microfabrication of Photonic Platforms
Springer Science and Business Media LLC - Tập 8 - Trang 395-408 - 2021
Luis Ricardo Mucciaroni, Marcelo Gonçalves Vivas
Laser Microfabrication (LMF) has been widely employed in a broad range of applications based on linear and nonlinear optics phenomena. Thus, this work aims to develop an Arduino-controlled low-cost LMF setup with high quality and precision. The LMF setup comprises a homemade optical microscope, a motorized 3-D translation stage based on low-cost stepper motors and current driver, and a relay modul...... hiện toàn bộ
