Feasibility on accurate measurement of non-uniform strain field through contact methods

Applications in Engineering Science, 2021
When straight material filaments do not remain straight after deformation, the strain varies spatially. These spatially varying strain fields arise because of (1) non-uniform distribution of boundary traction, (2) presence of residual stress in the ...

A strain-gauge random laser

APL Materials, 2019
We describe a random laser that uses the ZnO nanorods randomly orientated on a flexible polyimide (PI) substrate as disorderedly optical scatterers to stimulate coherent random lasing actions.

Dynamic and quasi-static signal separation method for bridges under moving loads based on long-gauge FBG strain monitoring

Journal of Low Frequency Noise, Vibration and Active Control, 2019
Structural health monitoring is an important means of obtaining the state information of bridges, and the extracted quasi-static strain signal can reflect the stress state of bridges directly.
