BEHAVIOR OF STEEL FIBER SELF-COMPACTING CONCRETE HOLLOW DEEP BEAMS UNDER TORQUE
Journal of Engineering and Sustainable Development, 2021 The purpose of this paper was concerned of the behavior of six samples of deep beams under the influence of pure torsion. Such samples were self-compacting concrete (SCC) and two ratios of Steel Fibers (SF (were also added (0.75 % and 1.5 %). This study

Deep learning for laser beam imprinting
Optics Express, 2023 Methods of ablation imprints in solid targets are widely used to characterize focused X-ray laser beams due to a remarkable dynamic range and resolving power. A detailed description of intense beam profiles is especially important in high-energy-density physics aiming at nonlinear phenomena. Complex interaction experiments require an enormous number of

Interaction time and beam diameter effects on the conduction mode limit [PDF]
, 2012 Laser welding has two distinctive modes: keyhole and conduction mode. Keyhole mode is characterized by deep penetration and high welding speeds, while conduction mode has higher quality welds with no defects or spatter.
