Effects of power modulation on behaviours of molten pool and keyhole during laser–arc hybrid welding of pure copper

Materials & Design, 2020
Modulated laser power hybrid welding (M-HW) of 4 mm-thick T2 pure copper was conducted to improve the welding stability. It was observed that the sinusoidal modulation of laser power in hybrid welding can reduce the incidence of weld defects such as ...

Mechanoethology: The Physical Mechanisms of Behavior [PDF]

Integrative and Comparative Biology, 2021
Abstract Research that integrates animal behavior theory with mechanics—including biomechanics, physiology, and functional morphology—can reveal how organisms accomplish tasks crucial to their fitness. Despite the insights that can be gained from this interdisciplinary approach, biomechanics commonly neglects a behavioral context and ...
