RBF-Slip behaviour of reinforced concrete elements subjected to corrosion of rebar

Case Studies in Construction Materials, 2020
Proper bond between rebar and concrete ensures efficient load transfer between rebar and surrounding concrete in reinforced concrete (RC) element. Corrosion of rebar reduces bond strength of RC element. Retained bond factor (RBF) describes bond retention

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
