Description
Wenying Xu and co-authors design in a 2026 study a light lattice that soaks up impact blows. The lattice form, based on smooth periodic surfaces, suits aerospace buffers, but fine models cost much compute time. Even designs can spike stress when they crush flat under load.
Their voxel based model cuts run time from 4,222 seconds to 497 against a fine mesh. A check picked a voxel size with just 1.11% error in density. Three lattice forms were screened at three densities, then mixed in a two slope design. In a set impact test, the mixed design cut peak stress by 32.2% against an even rival. It kept total soak near equal while crushing in a slower, staged way.
