A matrix-free, differentiable PyTorch solver for phase-field fracture: Formulation, benchmarks, and inverse analysis
Allamaprabhu Ani, Jean-François Molinari, Ghatu Subhash +1
A matrix-free, open-source PyTorch solver is presented for phase-field fracture on central processing units (CPUs) and graphics processing units (GPUs) without custom compiled exte…
Stability of Extrinsic Cohesive-Zone Model with Penalty-Based Contact in Explicit Dynamic Fragmentation Simulations
Thibault Ghesquière-Diérickx, Jean-François Molinari, Guillaume Anciaux
Dynamic fragmentation simulations are essential for predicting material response at high strain rates, yet explicit dynamic simulations that combine an extrinsic cohesive-zone mode…
Do Slip-Weakening Laws Shapes Influence Rupture Dynamics?
Roxane Ferry, Jean-François Molinari
To model rupture dynamics, a friction law must be assumed. Commonly used constitutive laws for modeling friction include slip-weakening laws which are characterized by a drop from…
A finite geometry, inertia assisted coarsening-to-complexity transition in homogeneous frictional systems
Thibault Roch, Efim A. Brener, Jean-François Molinari +1
The emergence of statistical complexity in frictional systems, manifested in broad distributions of various observables, is not yet understood. We study this problem in velocity-dr…
Role of minimum adhesive wear particle size in third-body layer properties
Son Pham-Ba, Jean-François Molinari
We employ a novel discrete element method (DEM) force formulation to simulate adhesive wear and assess the effects of material and loading parameters on the properties of the third…
Mesh d-refinement: a data-based computational framework to account for complex material response
Sacha Wattel, Jean-François Molinari, Michael Ortiz +1
Model-free data-driven computational mechanics (DDCM) is a new paradigm for simulations in solid mechanics. The modeling step associated to the definition of a material constitutiv…
