MAGTWIST: A Magnetically‐Driven Rotary Actuator Using a Traveling‐Wave With Integrated Stiffness Tunability

open access: yesAdvanced Functional Materials, EarlyView.
MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Impact mechanics of multilayer composite armors: Analytical modeling, FEM numerical simulation, and ballistic experiments

open access: yesComposite Structures, 2022
An analytical model is developed to study the ballistic behavior of multilayer composite armors subjected to the high-velocity impact of projectiles with arbitrary angle of incidence, shape, size, and frictional characteristics. The thickness compaction resulting from the production process is also accounted for, quantifying the role of the curing ...
