Atomistic Construction of Silicon Nitride Ceramic Fiber Molecular Model and Investigation of Its Mechanical Properties Based on Molecular Dynamics Simulations

Yiqiang Hong,
Yu Zhu,
Youpei Du
et al.

Abstract: Molecular simulations are currently receiving significant attention for their ability to offer a microscopic perspective that explains macroscopic phenomena. An essential aspect is the accurate characterization of molecular structural parameters and the development of realistic numerical models. This study investigates the surface morphology and elemental distribution of silicon nitride fibers through TEM and EDS, and SEM and EDS analyses. Utilizing a customized molecular dynamics approach, molecular models of… Show more

“…22) The structure of the SiNx bond network determined the mechanical properties of SiNx, 39) and its breakage led to a decrease in tensile strength. 40) Therefore, the thickness of this damaged layer was one of the factors that resulted in the decreased burst pressure of the SiNx membrane. In the case of the GCIB condition used in this experiment, the penetration depth was shallower compared with that during Ar + ion bombardment.…”
