Curvature Ductility of High Strength Concrete Beams [PDF]

, 2017
The ductility of reinforced concrete beams is very important, because it is the property that allows structures to dissipate energy under seismic loading, consequently, the brittle fractures of reinforced concrete structures can avoided.

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.
