Field data reconstruction and upper ocean circulation variability in tropical Indo-Pacific [PDF]

open access: yes, 2023
Yan, Xiao-HaiObservations are fundamental for studying and understanding the oceans. While in-situ measurements are limited, satellites can remotely monitor the ocean continuously for extended periods with broad spatial coverages.

Identification of viscoplastic parameters and characterization of Lüders behaviour using digital image correlation and the virtual fields method [PDF]

open access: yes, 2008
In this study, tensile loading experiments are performed on notched steel bars at an average applied strain rate of 1s-1. Displacement fields are measured across the specimen by coupling digital image correlation (DIC) with imaging using high speed CCD ...

Isochromatic-Art: A Computational Dataset for Digital Photoelasticity Studies

open access: yesData, 2022
The importance of evaluating the stress field of loaded structures lies in the need for identifying the forces which make them fail, redesigning their geometry to increase the mechanical resistance, or characterizing unstressed regions to remove material.

Optoacoustic inversion via convolution kernel reconstruction in the paraxial approximation and beyond

open access: yesPhotoacoustics, 2019
In this article we address the numeric inversion of optoacoustic signals to initial stress profiles. Therefore we study a Volterra integral equation of the second kind that describes the shape transformation of propagating stress waves in the paraxial ...
