Investigation of the hysteresis behavior of a convex column brace based on buckling mode transition mechanism

open access: yesAdvances in Mechanical Engineering, 2019
Brace structures with nonlinear stiffness are attractive in vibration mitigation. A new brace consisting of a novel convex column, which is characterized by the addition of a bulge structure compared to a column with constant cross-section, is proposed ...

Vibrating Air Column of High Frequency [PDF]

open access: yesNature, 1929
IN the course of some experiments recently carried out in these laboratories, a curious series of annular markings was observed in a glass tube through which air, carrying water-vapour and powered charcoal, was passing under diminished pressure. The accompanying photograph (Fig.

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization

open access: yesAdvanced Engineering Materials, EarlyView.
Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Application of tuned liquid column ball damper (TLCBD) for improved vibration control performance of multi-storey structure.

open access: yesPLoS ONE, 2019
Tuned liquid column ball damper (TLCBD) is a passive control device used for controlling the building vibrations induced from wind or earthquakes. TLCBD is a modified form of conventional tuned liquid column damper (TLCD).
