“…19 Moreover, for foam-type materials, the application of neural networks architectures to address their stress response have been reported where no mechanical models exist before: in their work, Sun-Woh and Somchai (1997) used a two hidden layer neural network model to predict the cushioning curves of EPS foams covering two different supplier materials and densities ranging from 18 to 30 kg/normalm3. 20 On foam materials, a more recent study by Weng et al., 21 presents the application of feed-forward neural network models to describe the stress/strain relation in grey cast iron during nanoindentation. Examples of the use of ANNs on modeling different material parameters than the stress/strain relationship, within the mechanics and materials science topics, can be found in the works by Mortazavi and Ince (mechanical fatigue), 22 Setti and Rao, Egala et al., (tribological behavior), 23,24 and Tabaza et al.…”

“…With the development of computer technology and artificial intelligence, combining machine learning and nanoindentation also inspires motivation to study material properties. Recently, Weng et al [45] studied the material properties of cast iron based on machine learning and FE nanoindentation simulation and extracted the sharp stress-strain curve of cast iron by proposing the optimization algorithm particle swarm optimization (PSO) and the detailed steps of the stress-strain relationship inversion method are summarized in Figure 5. Laxmikant et al [46] found that during the fabrication of electronic components, the mismatch in lattice and thermal expansion coefficients between the film and the substrate can lead to misfit strain.…”

“…Huber et al [127,128] used FEM-trained NNs to identify the Poisson's ratio of materials exhibiting plasticity with isotropic hardening, something not easily obtained before. Since then, FEM-trained NNs have been widely applied as an inverse algorithm to identify material properties from nanoindentation [222,223,224,225,226,227,228,229,230,231].…”
