Exploring the structure-property relations of thin-walled, 2D extruded lattices using neural networks
[article]
2022
arXiv
pre-print
Preserved Fulltext
This paper investigates the structure-property relations of thin-walled lattices under dynamic longitudinal compression, characterized by their cross-sections and heights. ...
Using an autoencoder, we encoded the cross-sectional images of the lattices into latent design feature vectors, which were supplied to the neural network model to generate predictions. ...
