RISTuning the Nonlinear Mechanical Anisotropy of Layered Crystals via Interlayer Twist
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multilayer graphene exhibits strong mechanical anisotropy in the nonlinear elastic regime, and tuning this mechanical anisotropy without damaging the graphene is a tough challenge. In this work, we propose an efficient ...
Grooving of Metals by High-Intensity Focused Ultrasound-Assisted Water-Confined Laser Micromachining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser grooving (i.e., the production of surface grooves through laser machining) has several advantages and many current or potential industrial applications. However, conventional laser grooving in air may often suffer ...
Deburring Effect of Plasma Produced by Nanosecond Laser Ablation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an interesting nanosecond (ns) laserinduced plasma deburring (LPD) effect (from microchannel sidewalls) discovered by the authors, which has been rarely reported before in the literature. Fast imagining ...
Microhole Drilling by High-Intensity Focused Ultrasound-Assisted Water-Confined Laser Micromachining
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Laser micromachining has several advantages such as the capability of flexibly producing very small features in both conductive and nonconductive materials. However, it may often suffer from induced defects, such as debris ...
Arbitrarily Patterned Active Wrinkles in Highly Stretched Substrate-Free Dielectric Elastic Membrane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Dynamic wrinkle patterns provide an effective approach for on-demand tuning of membrane optical and mechanical properties to realize a smart membrane. Related applications depend on forming and controlling of a sophisticated ...
MicroRNA-29a Involvement in Phenotypic Transformation of Venous Smooth Muscle Cells Via Ten–Eleven Translocation Methylcytosinedioxygenase 1 in Response to Mechanical Cyclic Stretch
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mechanical stimuli play an important role in vein graft restenosis and the abnormal migration and proliferation of vascular smooth muscle cells (VSMCs) are pathological processes contributing to this disorder. Here, based ...
Preliminary Experimental Study of Warm Ultrasonic Impact-Assisted Laser Metal Deposition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A preliminary experimental study on “warm ultrasonic impact-assisted laser metal deposition” (WUI-LMD) is reported, and such a study is rare in literature to the authors’ knowledge. In WUI-LMD, an ultrasonic impact treatment ...
Ultrasonic Cavitation Peening of Stainless Steel and Nickel Alloy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultrasonic cavitation peening is a peening process utilizing the high pressure induced by ultrasonic cavitation in liquids (typically water). In this paper, ultrasonic cavitation peening on stainless steel and nickel alloy ...
Microhole Drilling by Double Laser Pulses With Different Pulse Energies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous investigations on “double-pulse” nanosecond (ns) laser drilling reported in the literature typically utilize double pulses of equal or similar pulse energies. In this paper, “double-pulse” ns laser drilling using ...
