Seismic Behavior of a Steel Beam-to-Concrete-Filled Steel Tubular Column Connection Using External Diaphragms

open access: yesApplied Sciences, 2022
This paper investigates the seismic behavior of a steel beam-to-concrete-filled steel tubular column connection with external diaphragms. In addition to the multiple advantages observed for manufacturing and assembly, this type of connection is expected ...

An efficient strategy for producing RNA‐free Nucleocapsid protein of SARS‐CoV‐2 for biochemical and structural investigations

open access: yesFEBS Open Bio, EarlyView.
Cleavable N‐terminal Thioredoxin fusion enabled soluble expression and purification of otherwise insoluble SARS‐CoV‐2 Nucleocapsid (N) protein. A four‐step purification strategy yielded highly homogeneous, RNA‐free N protein. Binding assays showed high RNA affinity (Kd ~ 28 nm). The study will facilitate high‐resolution structural studies of N protein,

Thermomechanical Fatigue of Lost Foam Cast Al–Si Cylinder Heads—Assessment of Crack Origin Based on the Evaluation of Pore Distribution

open access: yesMetals, 2019
In automotive cylinder heads, thermomechanical fatigue (TMF) leads to crack initiation within the critical loaded sections. This effect becomes even more relevant in lost foam cast cylinder heads since its system-dependent porosity shows a significant ...

Development of a fretting-fatigue mapping concept: The effect of material properties and surface treatments [PDF]

open access: yes, 2009
Fretting-fatigue induced by combined localized cyclic contact motion and external bulk fatigue loadings may result in premature and dramatic failure of the contacting components.

The fatigue conundrum [PDF]

open access: yesBrain, 2017
Fatigue is a major affective symptom in neurological disease, but its basis is poorly understood. Kuppuswamy describes the defining features of fatigue and its relationship to perceived effort, before proposing that pathological fatigue is a consequence of impaired sensory attenuation.

Learning and Development Through the Scholarship of Teaching and Learning

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT This article focuses on learning that can facilitate the transition from being a scholarly teacher to becoming a scholar of teaching and learning, outlining the critical steps faculty can take to deepen their engagement with the scholarship of teaching and learning (SoTL).

Multi-joint and Large Load Wing Load Processing Method

open access: yesHangkong gongcheng jinzhan, 2020
For test piece lacking the right outer wing portion, the many and complicated butt joints, and the large test load, will bring great difficulty to the application of the wing load. Therefore the independent loading clamp is designed for the three sets of

Experimental analysis of the fatigue life of threaded pipe connections under cyclic bending [PDF]

open access: yes, 2012
When subjected to cyclic loads, fatigue cracks can cause failure of pipe systems joined by threaded pipe connections. In this study, the effect of contact conditions and coupling geometry is investigated experimentally. Fatigue tests under cyclic bending

Anisotropic elastic–plastic properties of surface-modified layers of 18CrNiMo7-6 alloy steel after carburizing heat treatment determined by an indentation method

open access: yesJournal of Materials Research and Technology, 2022
This work considers the analytical solution of the contact problem between a conical indenter and a transversely isotropic material, and uses a finite element method to determine the correction coefficient to implement in the analytical solution ...

High-resolution 3D weld toe stress analysis and ACPD method for weld toe fatigue crack initiation [PDF]

open access: yes, 2019
Weld toe fatigue crack initiation is highly dependent on the local weld toe stress-concentrating geometry including any inherent flaws. These flaws are responsible for premature fatigue crack initiation (FCI) and must be minimised to maximise the fatigue
