CRACKS IN REINFORCED CONCRETE BEAM

BALANGA: Jurnal Pendidikan Teknologi dan Kejuruan, 2022
Cracks in concrete cannot be prevented but the size of the cracks can be controlled. Cracks that occur in concrete are strongly influenced by the nature and characteristics of the concrete constituent materials, especially cement and water. Cracks can occur in the fresh and hard concrete phases.

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.

Unveiling the flexural strength of corroded prestressed self compacting concrete beams enhanced with M-sand and polypropylene fibres

Scientific Reports
Prestressing steel corrosion is one of the barriers to the serviceability of prestressed concrete structures. The presence of aggressive environmental conditions leads to a reduction in the efficiency of the structures by degradation.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...
