The role of static shear stress on forms of cyclic liquefaction

, 2016
There are divergent opinions on the effect of static shear stress on resistance to cyclic liquefaction of granular soils. For sand with fines, these issues are even more complicated as it relates to use of an‘equivalent’ initial state parameter in ...

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

Multiscale Coupling of Phase Transition and Urban Flow in Two‐Phase Chlorine Dispersion in Street Canyons

Safety Science and Technology, EarlyView.
A multiscale CFD framework reveals that two‐phase effects fundamentally alter hazardous gas dispersion in urban street canyons. Droplet evaporation, vortex‐driven transport, and ventilation jointly control hazard evolution, with wind speed dominating dispersion while temperature plays a secondary role.

Membrane Gas Separation for CO2 Capture From Flue Gas: Materials, Modules, Processes, and Application Prospects for Coal‐Fired Power Plant Retrofitting

Safety Science and Technology, EarlyView.
This review systematically covers the full CO₂ flue gas membrane separation chain, finding it cuts energy use by ∼30% versus amine methods, yet faces stability and cost hurdles for large‐scale application. ABSTRACT As global climate change becomes increasingly severe, carbon capture, utilization, and storage (CCUS) technologies have emerged as a ...

Assessing Static Liquefaction Triggers in Tailings Dams Using the Critical State Constitutive Models CASM and NorSand

Static liquefaction-induced failure in tailings dams can result in extensive economic and environmental damage. In practice, the use of constitutive models capable of capturing this phenomenon and assessing structures susceptible to liquefaction is ...

Post‐earthquake field assessment and damage correlation of elevated reinforced concrete water tanks in Kahramanmaras/Elbistan, Türkiye

Structural Concrete, EarlyView.
Abstract This study evaluates the seismic performance of elevated reinforced concrete (RC) water tanks in the Elbistan region following the February 6, 2023 Kahramanmaras–Elbistan earthquakes. Field investigations, visual damage surveys, non‐destructive testing (ultrasonic pulse velocity—UPV), concrete compressive strength measurements, peak ground ...
