Phantom-node method for shell models with arbitrary cracks

T Chau-Dinh, G Zi, PS Lee, T Rabczuk, JH Song - Computers & Structures, 2012 - Elsevier
A phantom-node method is developed for three-node shell elements to describe cracks. This
method can treat arbitrary cracks independently of the mesh. The crack may cut elements …

Efficient coarse graining in multiscale modeling of fracture

PR Budarapu, R Gracie, SW Yang, X Zhuang… - Theoretical and Applied …, 2014 - Elsevier
We propose a coarse-graining technique to reduce a given atomistic model into an
equivalent coarse grained continuum model. The developed technique is tailored for …

An adaptive multiscale method for quasi-static crack growth

PR Budarapu, R Gracie, SPA Bordas… - Computational …, 2014 - Springer
