Calibration Model Optimization for Strain Metrology of Equal Strength Beams Using Deflection Measurements

Sensors, 2023
Strain sensors, especially fiber Bragg grating (FBG) sensors, are of great importance in structural health monitoring, mechanical property analysis, and so on. Their metrological accuracy is typically evaluated by equal strength beams.

Investigation into the Multistage Mechanical Damage Behavior of Columnar Jointed Basalts with Different Meso-Constitutive Relations and Model Sizes [PDF]

Lithosphere, 2023
The mechanical characteristics of columnar jointed basalts (CJBs) are generally considered to be subject to size effects. They display complex mechanical behaviors under lateral pressure, which may be related to the variation in the rock's mesoproperties.

Influence of viscoelastic property of adhesive material on evaluation of peel strength

Nihon Kikai Gakkai ronbunshu, 2015
Peel test is widely used to evaluate interfacial strength of adhesive tape. The interface strength is usually obtained by subtracting energy consumed for plastic deformation of substrate film from external work for peeling.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Analysis of the influence of girth weld strength matching on pipe deformation mode and failure pattern

Journal of Pipeline Science and Engineering
A theory model with two kinds of material, which are used to describe the axis stress strain relationship of the pipe segment and girth weld joints, is proposed for the pipeline axial deformation analysis, and a pipeline deformation diagram is composed ...

Dynamic crushing of double-arrowed auxetic structure under impact loading

Materials & Design, 2018
Double-arrowed auxetic (DAA) structures with a negative Poisson's ratio have recently drawn increasing attention. This paper deduces the empirical formula of critical impact velocity to characterize the deformation modes of the DAA structures in two in ...
