Bending of kerf chiral fractal lattice metamaterials [PDF]
Composite Structures, 2023 We describe the out-of-plane bending of kerf chiral fractal lattices metamaterials by using a combination of theoretical models, full-scale finite elements and experimental tests representing the flexural behaviour of metamaterial beams under three-point bending. Good agreement is observed between the three sets of results.

Simulation and Experimental Research on Liquid Spreading in a Wire-Sawn Kerf
Chinese Journal of Mechanical Engineering, 2023 The significance of liquids in abrasive wire sawing has been demonstrated in several studies. However, the performance of its spreading behavior is limited by the current development trend, where the wafer has a larger area and the kerf is narrower ...
