Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Effect of hydrogen embrittlement on mechanical properties of non-stressed prestressing steel
Acta Polytechnica CTU ProceedingsThe aim of this paper is to elucidate the effect of hydrogen on the structure of commonly used prestressed concrete steel strand (PC strand) of concrete bridges and other structures in the non-stressed state to determine the general behaviour of the ...

Investigation of Subpanel Size Effect on Behavior Factor of Stiffened Steel Plate Shear Wall [PDF]
Journal of Structural and Construction Engineering, 2019 Steel plate shear wall (SPSW) systems have been used in recent years in highly seismic areas to resist lateral loads. In general, a steel plate shear wall system consists of a steel plate wall, boundary columns, horizental floor beams and optional ...

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Probabilistic assessment of steel moment frames incremental collapse (ordinary, intermediate and special) under earthquake [PDF]
Journal of Structural and Construction Engineering, 2017 Building collapse is a level of the structure performance in which the amount of financial and life loss is maximized, so this event could be the worst incident in the construction.

Advanced Engineering Materials, EarlyView.Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the
