Contact and fracture in the material point method require grid‐scale enrichment or
partitioning of material into distinct velocity fields to allow for displacement or velocity …

The material point method is well suited for large‐deformation problems in solid mechanics
but requires modification to avoid cell‐crossing errors as well as extension instabilities that …

We develop a local, implicit crack tracking approach to propagate embedded failure
surfaces in three-dimensions. We build on the global crack-tracking strategy of Oliver et …

We propose a weighted Nitsche framework for small-sliding frictional contact problems on
three-dimensional interfaces. The proposed method inherits the advantages of both …

This paper describes verification of a fully three-dimensional, massively parallel, finite
element based simulation framework (GEOS) for addressing the fully coupled, hydro …

Design decisions for the layout and properties of perforation clusters in a hydraulic fracture
stimulation job are typically based on idealizations that treat the fractures originating from …
