Multilevelk-way Partitioning Scheme for Irregular Graphs
George Karypis,Vipin Kumar +1 more
TL;DR: This paper presents and study a class of graph partitioning algorithms that reduces the size of the graph by collapsing vertices and edges, they find ak-way partitioning of the smaller graph, and then they uncoarsen and refine it to construct ak- way partitioning for the original graph.

A critical comparison of nonlocal and gradient-enhanced softening continua
TL;DR: In this paper, the effect of adding nonlocal or gradient terms to the constitutive modeling may enhance the ability of the models to describe such situations, and the relation between these enhancements are examined in a continuum damage setting.
