Shared metadata for data-centric materials science

Giovanni Pizzi, Ronald Earle Miller, Gian-Marco Rignanese, Carsten Baldauf, Matthias Scheffler, Tristan Bereau

The expansive production of data in materials science, their widespread sharing and repurposing requires educated support and stewardship. In order to ensure that this need helps rather than hinders scientific work, the implementation of the FAIR-data prin ...

Molecular dynamics at constant Cauchy stress

Ronald Earle Miller, Fabio Pavia

The Parrinello-Rahman algorithm for imposing a general state of stress in periodic molecular dynamics simulations is widely used in the literature and has been implemented in many readily available molecular dynamics codes. However, what is often overlooke ...

An energy balance criterion for nanoindentation-induced single and multiple dislocation events

William Curtin, Ronald Earle Miller

Small volume deformation can produce two types of plastic instability events. The first involves dislocation nucleation as a dislocation by dislocation event and occurs in nanoparticles or bulk single crystals deformed by atomic force microscopy or small n ...

Mesoscopic length scales for deformed nanostructures

William Curtin, Ronald Earle Miller

Defining mesoscopic length scales for deformed nanostructures requires a close coupling of theory and experiment. One approach to this is to mechanically probe single crystal nanospheres of the same size that can be evaluated computationally. This involves ...

Springer2006

Simulations of nanoindentation in single crystals are performed using a finite temperature coupled atomistic/continuum discrete dislocation (CADD) method. This computational method for multiscale modeling of plasticity has the ability of treating dislocati ...

A finite-temperature dynamic coupled atomistic/discrete dislocation method

William Curtin, Ronald Earle Miller

A method for simultaneously thermostatting an atomistic region and absorbing energetic pulses impinging on the atormstic/continuum interface from the atomistic region is developed to operate within the framework of the coupled atomistic/discrete dislocatio ...

A coupled atomistics and discrete dislocation plasticity simulation of nanoindentation into single crystal thin films

William Curtin, Ronald Earle Miller

The phenomenon of 2D nanoindentation of circular "Brinell" indenter into a single crystal metal thin film bonded to a rigid substrate is investigated. The simulation method is the coupled atomistics and discrete dislocation (CADD) model recently developed ...

2004

A computational method (CADD) is presented whereby a continuum region containing dislocation defects is coupled to a fully atomistic region. The model is related to previous hybrid models in which continuum finite elements are coupled to a fully atomistic ...

A study of nano-indentation using coupled atomistic and discrete dislocation (CADD) modeling

William Curtin, Ronald Earle Miller

The phenomenon of nano-indentation into a thin film bonded to a rigid substrate is simulated using a recently developed technique whereby a fully atomistic region is coupled to a continuum region. There are three unique features of the model, as compared t ...

Atomistic/continuum coupling in computational materials science

William Curtin, Ronald Earle Miller

Important advances in multi-scale computer simulation techniques for computational materials science have been made in the last decade as scientists and engineers strive to imbue continuum-based models with more-realistic details at quantum and atomistic s ...
