Proposed residual stress model for hot‐rolled wide flange steel cross sections
Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Andronikos Skiadopoulos
Residual stresses in hot-rolled wide flange steel cross sections may lead to premature yielding, accelerated corrosion and brittle fracture of steel members. The above phenomena lead to a loss of a steel member's stiffness and resistance under mechanical l ...
2023Crack kinematics prediction in concrete structures and assessment of their criticality
The observation of cracks in normally functioning reinforced concrete (RC) structures is expected as the tensile strength of concrete is relatively low. However, one or more of those cracks can start to propagate with increasing crack openings, localizing ...
2023Nanomechanical Modeling of the Bending Response of Silicon Nanowires
Yusuf Leblebici, Zuhal Tasdemir, Mohammad Nasr Esfahani, Mustafa Yilmaz
Understanding the mechanical behavior of silicon nanowiresis essentialfor the implementation of advanced nanoscale devices. Although bendingtests are predominantly used for this purpose, their findings shouldbe properly interpreted through modeling. Variou ...
AMER CHEMICAL SOC2023Experimental Evaluation and Modeling of Residual Stress Distributions for Hot-Rolled Wide Flange Steel Members
Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Andronikos Skiadopoulos
Local and member instability modes in structural steel members are influenced by initial geometric imperfections and residual stresses among other parameters. The robustness of stability-related design provisions and finite element modeling procedures of s ...
2023Database of Residual Stress Measurements on Hot-rolled Wide Flange Steel Cross Sections
Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa, Andronikos Skiadopoulos

Zenodo2023Fatigue behavior of transverse attachments under constant and variable amplitude loading from a Swiss motorway bridge
Alain Nussbaumer, Davide Leonetti, Yukina Takai
This paper investigates the fatigue behavior of non-load-carrying transverse welded steel attachments by reporting on an experimental characterization under constant and variable amplitude loading. Fatigue cracks have been monitored using DIC and ACPD tech ...
London2023Determining crack kinematics from imaged crack patterns
Katrin Beyer, Bryan German Pantoja Rosero, Amir Rezaie, Ketson Roberto Maximiano Dos Santos
Determining the relationship between the cause of damage and the subsequent structural behavior of infrastructure systems requires an accurate characterization of the propagation of cracks, which represents the evolution of the damage state. When no inform ...
ELSEVIER SCI LTD2022Laser powder-bed fusion of metallic alloys with enhanced microstructures and properties
Laser powder-bed fusion (LPBF) is an additive manufacturing (AM) process that uses a laser to selectively melt a powder bed. This process can build dense samples with complicated geometries from a wide variety of metallic alloys. In this thesis, LPBF of al ...
EPFL2021Experimental investigation of the cyclic properties of welds in mild structural steels
Structural steels have long been used in construction applications. Their mechanical properties and behavior under seismic loading or under fatigue design are of considerable interest for researchers and engineers. Although extensive studies have been cond ...
2021Investigation of residual stresses in planar dissimilar magnetic pulse welds by neutron diffraction
Residual stresses are investigated for the first time in a dissimilar AA1050-DP450 steel magnetic pulse weld using neutron diffraction. Close to the joint interface, tensile residual stresses are observed in the Al sheet and compressive residual stresses a ...
