Experimental and 3D Finite Element Studies of CW Laser Forming of Thin Stainless Steel Sheets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser forming as a springback-free and noncontact forming technique has been under active investigation over the last decade. Previous investigations are mainly focused on forming of large and ...
Finite Element Analysis of Pulsed Laser Bending: The Effect of Melting and Solidification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work developes a finite element model to compute thermal and thermomechanical phenomena during pulsed laser induced melting and solidification. The essential elements of the model are handling ...
High Precision Microscale Bending by Pulsed and CW Lasers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper discusses high precision microscale laser bending and the thermomechanical phenomena involved. The use of a pulsed and a CW laser for microscale bending of ceramics, silicon, and ...
Heat Transfer Across Metal-Dielectric Interfaces During Ultrafast-Laser Heating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Heat transfer across metal-dielectric interfaces involves transport of electrons and phonons accomplished either by coupling between phonons in metal and dielectric or by coupling between electrons ...
Palladium Thiolate Bonding of Carbon Nanotube Thermal Interfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Carbon nanotube (CNT) arrays can be effective thermal interface materials with high compliance and conductance over a wide temperature range. Here, we study CNT interface structures in which ...
Effects of Growth Temperature on Carbon Nanotube Array Thermal Interfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to their excellent compliance and high thermal conductivity, dry carbon nanotube (CNT) array interfaces are promising candidates to address the thermal management needs of power dense ...
