Fabrication of NiAl alloy hollow thin-walled component through hot gas forming of Ni/Al laminated tube and conversion process

open access: yesJournal of Materials Research and Technology, 2023
The NiAl intermetallic compounds have higher service temperature and lower density than traditional Ni-based super-alloy. In this work, for overcoming the fabricating bottleneck of NiAl alloy hollow thin-walled component, a typical NiAl alloy square ...

Swimming Mode of Two Interacting Squirmers under Gravity in a Narrow Vertical Channel

open access: yesEntropy, 2022
The swimming mode of two interacting squirmers under gravity in a narrow vertical channel is simulated numerically using the lattice Boltzmann method (LBM) in the range of self-propelling strength 0.1 ≤ α ≤ 1.1 and swimming type −5 ≤ β ≤ 5.

Hybrid phase-field modeling of multi-level concrete gravity dam notched cracks

open access: yesFracture and Structural Integrity, 2022
Phase-field models have become a powerful tool to simulate crack propagation. They regularize the fracture discontinuity and smooth the transition between the intact and the damaged regions. Based on the thermodynamic function and a diffusive field, they
