Numerical methods and improvements for simulating quasi-static elastoplastic materials

Jiayin Lu, Chris H. Rycroft

Hypo-elastoplasticity is a framework suitable for modeling the mechanics of many hard materials that have small elastic deformation and large plastic deformation. In most laborator…

An extension to VORO++ for multithreaded computation of Voronoi cells

Jiayin Lu, Emanuel A. Lazar, Chris H. Rycroft

VORO++ is a software library written in C++ for computing the Voronoi tessellation, a technique in computational geometry that is widely used for analyzing systems of particles. VO…

Voronoi cell analysis: The shapes of particle systems

Emanuel A. Lazar, Jiayin Lu, Chris H. Rycroft

Many physical systems can be studied as collections of particles embedded in space, evolving through deterministic evolution equations. Natural questions arise concerning how to ch…

Manifold learning for coarse-graining atomistic simulations: Application to amorphous solids

Katiana Kontolati, Darius Alix-Williams, Nicholas M. Boffi +3

We introduce a generalized machine learning framework to probabilistically parameterize upper-scale models in the form of nonlinear PDEs consistent with a continuum theory, based o…

Coordinate transformation methodology for simulating quasi-static elastoplastic solids

Nicholas M. Boffi, Chris H. Rycroft

Molecular dynamics simulations frequently employ periodic boundary conditions where the positions of the periodic images are manipulated in order to apply deformation to the materi…

Parallel three-dimensional simulations of quasi-static elastoplastic solids

Nicholas M. Boffi, Chris H. Rycroft

Hypo-elastoplasticity is a flexible framework for modeling the mechanics of many hard materials under small elastic deformation and large plastic deformation. Under typical loading…
