Lattice Boltzmann for linear elastodynamics: periodic problems and Dirichlet boundary conditions
Oliver Boolakee, Martin Geier, Laura De Lorenzis
We propose a new second-order accurate lattice Boltzmann formulation for linear elastodynamics that is stable for arbitrary combinations of material parameters under a CFL-like con…
Calibration and Validation of a Phase-Field Model of Brittle Fracture within the Damage Mechanics Challenge
Jonas Heinzmann, Pietro Carrara, Chenyi Luo +6
In the context of the Damage Mechanics Challenge, we adopt a phase-field model of brittle fracture to blindly predict the behavior up to failure of a notched three-point-bending sp…
Reduced and All-at-Once Approaches for Model Calibration and Discovery in Computational Solid Mechanics
Ulrich Römer, Stefan Hartmann, Jendrik-Alexander Tröger +4
In the framework of solid mechanics, the task of deriving material parameters from experimental data has recently re-emerged with the progress in full-field measurement capabilitie…
Phase-Field Modeling of Fracture with Physics-Informed Deep Learning
M. Manav, R. Molinaro, S. Mishra +1
We explore the potential of the deep Ritz method to learn complex fracture processes such as quasistatic crack nucleation, propagation, kinking, branching, and coalescence within t…
An adaptive acceleration scheme for phase-field fatigue computations
Jonas Heinzmann, Pietro Carrara, Marreddy Ambati +2
Phase-field models of fatigue are capable of reproducing the main phenomenology of fatigue behavior. However, phase-field computations in the high-cycle fatigue regime are prohibit…
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…
Dehydration drives damage in the freezing of brittle hydrogels
Shaohua Yang, Dominic Gerber, Yanxia Feng +6
It is widely known that freezing breaks soft, wet materials. However, the mechanism underlying this damage is still not clear. To understand this process, we freeze model, brittle…
