Examining the impact of sheet placement and changes in waves characteristics on behavior of wavy steel shear wall

open access: yesCase Studies in Construction Materials, 2018
Steel shear walls are usually constructed in two forms, solid and non-solid. Generally, the solid ones function better in terms of seismic performance and exploitation; however, their construction is costly and time-consuming due to the use of various ...

Modeling of pvT behavior of semi-crystalline polymer based on the two-domain Tait equation of state for injection molding

open access: yesMaterials & Design, 2019
The absence of the influence of cooling rate in the pressure–specific volume–temperature (pvT) models makes them inadequate in the process simulation of injection molding.

Tensile failure of fibre-metal-laminates made of titanium and carbon-fibre/epoxy laminates

open access: yesMaterials & Design, 2019
The tensile properties of the lightweight titanium-based carbon-fibre/epoxy laminates (TI-CF FMLs) were investigated under quasi-static loading. A comprehensive experimental study was conducted for eleven different types of the TI-CF FMLs (considering ...
