Earthquake Engineering &Structural Dynamics, Volume 54, Issue 4, Page 1229-1250, 10 April 2025.ABSTRACT Performance‐based seismic design, which emerged more than two decades ago, requires accurate numerical models to capture the response of structural elements that undergo inelastic deformations under random loading histories. High‐fidelity benchmark test results under real natural hazards are therefore required to assist researchers and ...

Earthquake Spectra, Volume 41, Issue 1, Page 608-635, February 2025.Observations from past earthquakes have highlighted the structural damage and significant residual deformations experienced by ductile steel seismic force‐resisting systems (SFRSs), such as special moment resisting frames (SMRFs), special concentrically braced frames (SCBFs), and buckling‐restrained braced frames (BRBFs).

Mathematical Methods in the Applied Sciences, Volume 48, Issue 1, Page 926-979, 15 January 2025.We employ the theory of asymptotic homogenization (AH) to study the elasto‐plastic behavior of a composite medium comprising two solid phases, separated by a sharp interface and characterized by mechanical properties, such as elastic coefficients and “initial yield stresses” (i.e., a threshold stress above which remodeling is triggered), that may ...

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.

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

The Bauschinger Effect in Structural Aluminum Alloys
Engineering Transactions, 1983 The paper presents test results for the Bauschinger effect on various structural aluminum alloys (PA7N, PA4N, PA2N). The experiments were carried out for the raw materiał, obtained directly from the factory. The rango of initial overstrain ew was 0.2 - 9%

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.

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.
