Study the Ductility of Aluminum Alloy Processed by Asymmetric Rolling Process [PDF]
Engineering and Technology Journal, 2020 Asymmetric rolling refers to the conditions wherein velocities or diameters of two work rolls are different. Compared to symmetrical rolling, asymmetric rolling is more effective on microstructure modification and texture evolution.

Laser additive manufacturing of titanium alloys with various Al contents
Materials Research Letters, 2023 Laser powder bed fusion (LPBF) is an additive manufacturing technology for metals. Ti-6Al-4V (Ti64) is a frequently used material for LPBF, but as-built LPBF-Ti64 has poor ductility that limits its usage.

Ductility and internal forces redistribution in lightweight aggregate concrete beams
Budownictwo i Architektura, 2020 Lightweight Aggregate Concrete (LWAC) is typically defined as concrete having a density smaller than or equal to 2200kg/m3 and can be obtained by mixing natural or artificial lightweight aggregates.

Regression Models for the Description of the Behaviour of Modern Timber Joints
Buildings, 2023 Joints in timber structures are today typically designed in a simplistic manner, i.e., by assuming linear elastic behaviour or neglecting their real stiffness by assuming ideal pinned or fixed conditions.

Effect of irregularity on seismic design parameters of RC-infilled structures
Magazine of Civil Engineering, 2021 A four-storey reinforced concrete (RC) building is seismically evaluated with the incorporation of different irregularities. Three model systems have been considered, i.e., model I: (RC-infilled regular frame in X and Y direction), model II: (RC-infilled
