Bar & Hinge reduced-order model enables fast, general kirigami simulation
ssh4net · x · 2026-08-20
Researchers Khawale, Mehdizadeh, Brigham and Filipov propose a generalized, computationally efficient reduced-order model based on the bar and hinge approach for simulating any kirigami (cut-sheet) system. Kirigami offers shape morphing, stretchability and adaptability for deployable/reconfigurable structures, but finite element analysis is computationally intensive and prone to convergence issues, while existing simplified models are restricted to specific designs. The new model represents the entire kirigami structure with truss bars and bending hinges, combining generality with speed.
