Influences of sequential cuts on micro-cutting process studied by smooth particle hydrodynamic (SPH)
TL;DR: In this paper, the effect of the cutting edge radius on residual stress was investigated and the simulation results showed that the chip curled severely and the minimum chip thickness decreased in the second cut because of residual stress in the machined surface after the first cut.

Probing the atomic-scale origins of anti-friction and wear-resisting in graphene-coated high-entropy alloys
TL;DR: In this article , the friction and wear behavior of multilayer graphene (Gr) reinforced high-entropy alloys (HEAs) matrix composite was analyzed through the molecular dynamics simulations.

Multi-field nanoindentation apparatus for measuring local mechanical properties of materials in external magnetic and electric fields
TL;DR: In this paper, a modularized multi-field nanoindentation apparatus for carrying out testing on materials in external magnetostatic/electrostatic field is constructed, and the load-displacement curves of ferromagnetic, ferroelectric and magnetoelectric materials in the presence/absence of external fields reveal the small-scale magnetomechanical and electromechanical coupling, showing as the ΔE and ΔHin effects, i.e., the magnetic/electric field induced changes in the apparent elastic modulus and indentation hardness.

Experimental investigation on the ultrasonically assisted single-sided lapping of monocrystalline SiC substrate
TL;DR: In this paper, the effect and optimization of ultrasonically assisted single-sided lapping for monocrystalline SiC wafer using grey relational analysis method was studied by investigating the correlation between them.
