Anchorage System Contribution to Post‐Tensioned Bridge Collapse
Engineering Reports, Volume 8, Issue 5, May 2026.This paper presents an experimental investigation of a 1960s precast post‐tensioned girder bridge in Trstena, Slovakia, revealing severe corrosion and anchorage degradation that ultimately led to its collapse. The findings highlight critical vulnerabilities in obsolete anchorage systems and emphasize the need for proactive assessment and maintenance of

steel research international, Volume 97, Issue 3, Page 1369-1383, March 2026.The processability of the E11018‐G by laser powder directed energy deposition (LP‐DED) is investigated. The effects of powder moisture, ambient humidity, and laser remelting on LP‐DED parts’ porosity are shown. A strong influence of the atomizing gas is observed.

Nature of delamination cracks in pearlitic steels
Scripta Materialia, 2016 AbstractWire-drawn fully pearlitic steel was twisted at room temperature. As a result, a delamination crack propagated along the longitudinal direction of the wire. Backscattered electron and transmission electron microscopy images indicated that the cementite lamellae beneath the delamination crack had vanished.

Wind Energy, Volume 29, Issue 1, January 2026.ABSTRACT Reliability, safety, and the lifetime of wind energy systems are mainly driven by the quality of each single component. Especially, large structures made of cast material or welded structures, such as the nacelle, the machine carrier, or the tower, are subjected to cyclic loading.

Altering the microstructure of pearlitic steel using pulsed electric current
, 2015 Pearlitic steel is widely used in many industries due to its inherent strength and toughness. It can have a tensile strength in excess of 6GPa in the cold- drawn state [1] and its properties and machinability can be altered through heat treatments, such ...

Advanced Engineering Materials, Volume 27, Issue 24, December 2025.This study presents a 3D representative volume element‐based simulation approach to predict mesoscopic residual stress and strain fields in silicon solid solution‐strengthened ductile cast iron. By modeling phase transformation kinetics with an enhanced Johnson–Mehl–Avrami–Kolmogorov model, the effects of varying cooling rates on residual stresses are ...
