Digital holographic photoelasticity

Applied Optics, 2017
A new technique using digital holography to study the photoelastic isochromatic and isopachic fringes and their respective phases is reported. Our detailed theoretical and experimental analysis shows the possibility of whole-field analysis of every section of stressed photoelastic materials.

PhotoelastNet: a deep convolutional neural network for evaluating the stress field by using a single color photoelasticity image.

Applied Optics, 2022
Quantifying the stress field induced into a piece when it is loaded is important for engineering areas since it allows the possibility to characterize mechanical behaviors and fails caused by stress.

Experimental study of dry stone masonry walls using digital reflection photoelasticity

Strain, 2020
Response of dry stack stone masonry walls under mechanical loading is complex and difficult to determine, mainly due to heterogeneous and discrete nature of the components of the stone wall.

Generalized adversarial networks for stress field recovering processes from photoelasticity images

Optical Engineering + Applications, 2020
For overcoming conventional photoelasticity limitations when evaluating the stress field in loaded bodies, this paper proposes a Generative Adversarial Network (GAN) while maintaining performance, gaining experimental stability, and shorting time ...
