Axial-flexural coupled vibration and buckling of composite beams using sinusoidal shear deformation theory

open access: yes, 2013
A finite element model based on sinusoidal shear deformation theory is developed to study vibration and buckling analysis of composite beams with arbitrary lay-ups.

Dynamic Characteristics Analysis of Three-Layer Steel–Concrete Composite Beams

open access: yesBuildings
The dynamic behavior of three-layer composite beams, consisting of concrete slabs and steel beams, is influenced by the structural configuration of each layer as well as the shear connectors.

Determination of the effectivity of composite members on structural behavior through different combinations

open access: yesCase Studies in Construction Materials, 2022
The majority of the existing building stock has reinforced concrete load-bearing systems and relatively few buildings are steel-framed. On the other hand, composite frames are less preferred compared to these two types of structures.

Geometrically nonlinear analysis of thin-walled open-section composite beams

open access: yes, 2010
A geometrically nonlinear model for general thin-walled open-section composite beams with arbitrary lay-ups under various types of loadings based on the classical lamination theory is presented.

Flexural-torsional behavior of thin-walled closed-section composite box beams

open access: yes, 2007
This paper presents a flexural–torsional analysis of composite box beams. A general analytical model applicable to thin-walled box section composite beams subjected to vertical and torsional load is developed.

On Isospectral Composite Beams

open access: yesApplied Sciences, 2023
We consider a composite system consisting of two identical straight elastic beams under longitudinal vibration connected by an elastic interface capable of counteracting the relative vibration of the two beams with its shearing stiffness. We construct examples of isospectral composite beams, i.e., countable one-parameter families of beams having ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Significance of low energy impact damage on modal parameters of composite beams by design of experiments [PDF]

open access: yes, 2009
This paper presents an experimental study on the effects of multi-site damage on the vibration response of composite beams damaged by low energy impacts around the barely visible impact damage limit (BVID).

An Assessment of the Behaviour of Ceiling Beams of Different Structure

open access: yesApplied Sciences
The article focuses on floor composite beams used in buildings. Within the scope of the conducted analytical and numerical studies, the authors compared the typical solution—namely, the T-shaped reinforced concrete beam—with various types of composite ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
