JOR SPINE, Volume 9, Issue 3, September 2026.ABSTRACT Background Subaxial cervical facet dislocation (CFD) is a severe neck injury associated with head‐first impact (HFI). However, CFD has not been reliably reproduced in experimental or numerical studies, limiting understanding of its underlying mechanics.

Explicit Dynamics Analysis of the Impact Response of Lithium‐Ion Cells
Macromolecular Symposia, Volume 415, Issue 4, August 2026.ABSTRACT It is very important to make sure that EV lithium‐ion cells are safe when they are abused, like when they are hit or crushed. This kind of loading can cause structural failure or thermal runaway. Even though FEA is used a lot, common practices make the jellyroll the same and ignore the fact that the electrolyte is a moving fluid.
