Enhancing the Performance of Concrete Coupled Shearwall Using Shape Memory Alloys
Engineering Reports, Volume 7, Issue 1, January 2025.In this study, shape memory alloys as rebar are utilized in order to improve the self‐centering ability of reinforced concrete structures subjected to seismic excitation. Two cases of enhancing system for the location of shape memory alloys to be utilized are proposed. The first case is the energy dissipation‐residual drift scenario, and the second one

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.Inclined reinforced concrete (RC) piers, common in mountainous highway bridges, can exhibit heightened seismic vulnerability. We investigate inclination–damage mechanisms using a fiber‑based OpenSees model combined with a hierarchical damage quantification framework.

Novel Capacity‐Adjustable BRB for Improving the Seismic Performance of Tall‐Pier Bridges
Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.Tall‐pier bridges are commonly employed in mountainous or deep‐water regions. Ensuring the postearthquake serviceability is crucial for the seismic design of tall‐pier bridges. Buckling‐restrained braces (BRBs), serving as prevalent replaceable energy‐dissipating components, can effectively enhance the seismic performance of such bridges.

The detrimental effect of autofrettage on externally cracked modern tank gun barrels
Defence Technology, 2019 Overstraining gun tubes has a twofold advantage. First, it enables the increase of the Safe Maximum Pressure (SMP) in the tube, resulting in a higher muzzle velocity which extends the gun's range and its projectile kinetic energy.

Inverse Bauschinger effect in active ultrastable glasses
Physical Review EMemory effects in amorphous materials have been widely studied because of their possible widespread future applications. We show here that ultrastable glasses can exhibit a transient reversible memory effect when subjected to both a local driving force via Run-and-tumble active particles and global shear.
