In this paper, we propose a novel method to develop biomimetic models using polyurethane elastomer, which has high photoelastic coefficient, and a method to analyze stress states on the model by ...

Dynamic photoelastic imaging technology is an important means to observe the ultrasonic stress field inside a solid. However, the sample will generate residual stress during the manufacturing process, ...

Recent work has shown that deep convolutional neural network is capable of solving inverse problems in computational imaging, and recovering the stress field of the loaded object from the photoelastic ...

3.2 Photoelastic Image Dataset It is expensive to obtain enough photoelastic fringe patterns and corresponding stress field images through the photoelastic experiment, which is due to the complicated ...

When using small photoelastic samples, these types of errors can escalate due to the increased difficulty of handling. Intending to minimize systematic errors in the process of data collection, this ...

A family of acrylate-based isotropic Liquid Crystal Elastomers (LCEs) exhibit stress- and strain-optic coefficients orders of magnitude greater than conventional polymeric and photoelastic materials.
