Fig. 1: Stress distribution in case of elastic material response.
From: Teaching solid mechanics to artificial intelligence—a fast solver for heterogeneous materials
Simulation results obtained by DAMASK in conjunction with a spectral solver (a) and the corresponding AI predicted (b) von Mises stress distribution for three Voronoi tessellations of test microstructures (not included in the training dataset) using the modified U-Net approach. The error, calculated as deviation between the two von Mises stress distributions, δSvM, is shown in (c).
