Automated identification of linear viscoelastic constitutive laws with EUCLID
- Computer Science
- 2022
EUCLID, a computational strategy for automated material model discovery and identification, is extended to linear viscoelasticity and shown to accurately identify a linear visCOelastic model out of a library with several hundreds of terms spanning relaxation times across seven orders of magnitude.
