The Language of Hyperelastic Materials
Georgios Kissas, Siddhartha Mishra, Eleni Chatzi +1
The automated discovery of constitutive laws forms an emerging research area, that focuses on automatically obtaining symbolic expressions describing the constitutive behavior of s…
Single-test evaluation of directional elastic properties of anisotropic structured materials
Jagannadh Boddapati, Moritz Flaschel, Siddhant Kumar +2
When the elastic properties of structured materials become direction-dependent, the number of their descriptors increases. For example, in two-dimensions, the anisotropic behavior…
Neural Cellular Automata for Solidification Microstructure Modelling
Jian Tang, Siddhant Kumar, Laura De Lorenzis +1
We propose Neural Cellular Automata (NCA) to simulate the microstructure development during the solidification process in metals. Based on convolutional neural networks, NCA can le…
Automated identification of linear viscoelastic constitutive laws with EUCLID
Enzo Marino, Moritz Flaschel, Siddhant Kumar +1
We extend EUCLID, a computational strategy for automated material model discovery and identification, to linear viscoelasticity. For this case, we perform a priori model selection…
Automated discovery of generalized standard material models with EUCLID
Moritz Flaschel, Siddhant Kumar, Laura De Lorenzis
We extend the scope of our approach for unsupervised automated discovery of material laws (EUCLID) to the case of a material belonging to an unknown class of behavior. To this end,…
Data-Driven Rate-Dependent Fracture Mechanics
Pietro Carrara, Michael Ortiz, Laura De Lorenzis
We extend the model-free data-driven paradigm for rate-independent fracture mechanics proposed in Carrara et al. (2020), Data-driven Fracture Mechanics, Comp. Meth. App. Mech. Eng.…
Cooperativity in the enhanced piezoelectric response of polymer nanowires
Luana Persano, Canan Dagdeviren, Claudio Maruccio +2
We provide a detailed insight into piezoelectric energy generation from arrays of polymer nanofibers. For sake of comparison, we firstly measure individual poly(vinylidenefluoride-…
