Data-Driven Games in Computational Mechanics
Kerstin Weinberg, Laurent Strainier, Sergio Conti +1
We resort to game theory in order to formulate Data-Driven methods for solid mechanics in which stress and strain players pursue different objectives. The objective of the stress p…
An optimal-transport finite-particle method for mass diffusion
Anna Pandolfi, Laurent Stainier, Michael Ortiz
We formulate a class of velocity-free finite-particle methods for mass transport problems based on a time-discrete incremental variational principle that combines entropy and the c…
Data-driven fracture mechanics
Pietro Carrara, Laura De Lorenzis, Laurent Stainier +1
We present a new data-driven paradigm for variational brittle fracture mechanics. The fracture-related material modeling assumptions are removed and the governing equations stemmin…
Model-free Data-Driven Computational Mechanics Enhanced by Tensor Voting
Robert Eggersmann, Laurent Stainier, Michael Ortiz +1
The data-driven computing paradigm initially introduced by Kirchdoerfer & Ortiz (2016) is extended by incorporating locally linear tangent spaces into the data set. These tangent s…
Model-Free Data-Driven Methods in Mechanics: Material Data Identification and Solvers
Laurent Stainier, Adrien Leygue, Michael Ortiz
This paper presents an integrated model-free data-driven approach to solid mechanics, allowing to perform numerical simulations on structures on the basis of measures of displaceme…
Effective transient behaviour of heterogeneous media in diffusion problems with a large contrast in the phase diffusivities
Laurence Brassart, Laurent Stainier
This paper presents a homogenisation-based constitutive model to describe the effective tran- sient diffusion behaviour in heterogeneous media in which there is a large contrast be…
Model-Free Data-Driven Inelasticity
Robert Eggersmann, Trenton Kirchdoerfer, Stefanie Reese +2
We extend the Data-Driven formulation of problems in elasticity of Kirchdoerfer and Ortiz (2016) to inelasticity. This extension differs fundamentally from Data-Driven problems in…
Effective transient behaviour of inclusions in diffusion problems
Laurence Brassart, Laurent Stainier
This paper is concerned with the effective transport properties of heterogeneous media in which there is a high contrast between the phase diffusivities. In this case the transient…
A Multiscale Approach for Modeling Crystalline Solids
A. M. Cuitino, L. Stainier, G. Wang +4
In this paper we present a modeling approach to bridge the atomistic with macroscopic scales in crystalline materials. The methodology combines identification and modeling of the c…
A Micromechanical Model of Hardening, Rate Sensitivity and Thermal Softening in BCC Single Crystals
Laurent Stainier, Alberto M. Cuitino, Michael Ortiz
The present paper is concerned with the development of a micromechanical model of the hardening, rate-sensitivity and thermal softening of bcc crystals. In formulating the model we…
