Strain field reconstruction of crossbeam structure based on load–strain linear superposition method
Smart Materials and Structures, 2021Abstract To address the problem that sensors cannot be affixed at certain critical locations of the crossbeam structure and the full-field strain distribution cannot be obtained in real-time. In this paper, a strain field reconstruction algorithm based on the load–strain linear superposition method is proposed to reconstruct the ...

Non-uniform strain field reconstruction of FBG using an adaptive Nelder–Mead algorithm
Optics Communications, 2021Abstract This paper presents an adaptive Nelder–Mead algorithm to inversely reconstruct the non-uniform strain field from the reflected intensity spectrum of the fiber grating sensor. In this algorithm, the standard operating parameters are modified to adapt to the variable strain profiles, and an improved transfer matrix method is adopted to rapidly

Strain field reconstruction in shallow trench isolation structures by CBED and LACBED
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2006Using a combination of the CBED and the LACBED techniques in the transmission electron microscopy (TEM), we have investigated the strain field in the silicon active region of a shallow trench isolation structure, underlying a TiSi2 layer. Starting from the analysis of the deformation in a sample, thinned for TEM analysis, we have reconstructed the ...

Strain field sensing and reconstruction for a thin-wall plate
2016 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), 2016Deformation and vibration of thin-wall workpieces during machining could induce residual stresses in the final products, which makes real-time monitoring of the strain field critical to optimizing machining process and minimizing workpiece stresses. However, traditional methods based on strain-gauge measurements are inapplicable because materials are ...

Full-field dynamic strain reconstruction of rotating compressor blades based on FBG sensors
Smart Materials and StructuresAbstract Rotating compressor blades experience complex alternating loads during service, altering their stress–strain distributions and peak stress positions over time. Accurate measurement of these strains is crucial for identifying the areas of stress concentration.
