Journal ArticleDOI
Size effects in foams: Experiments and modeling
TL;DR: In this paper, two-dimensional (2D) Voronoi tessellations are used to represent random foams, and four representative boundary value problems are solved by the finite element (FE) method.
Journal ArticleDOI
The growth and coalescence of ellipsoidal voids in plane strain under combined shear and tension
TL;DR: In this article, a model for the growth and coalescence of ellipsoidal voids based on the Gurson formalism is proposed in order to treat problems involving shear and/or voids axis not necessarily aligned with the main loading direction, under plane strain loading conditions.
Journal ArticleDOI
On localization and void coalescence as a precursor to ductile fracture
TL;DR: A three-dimensional elastic–plastic computational model representing a doubly periodic array of voids within a band confined between two semi-infinite outer blocks of the same material but without voids predicts that the onset of macroscopic localization and coalescence occur simultaneously.
Journal ArticleDOI
Size effects in two-dimensional Voronoi foams: A comparison between generalized continua and discrete models
Cihan Tekoglu,Patrick Onck +1 more
TL;DR: In this paper, the analytical results of generalized continuum theories with the computational results of discrete models are studied from two classes of generalized continuous theories: the strain divergence theory from the class of higher-grade continua and the micropolar theory from higher-order continua.
Journal ArticleDOI
Void growth and coalescence in single crystals
Kumar Yerra Sampath,Kumar Yerra Sampath,Cihan Tekoglu,Florence Scheyvaerts,Laurent Delannay,Paul Van Houtte,Thomas Pardoen +6 more
TL;DR: In this paper, the Thomason void coalescence criterion was used to predict the onset of void growth and coalescence in a unit cell involving a single spherical void and fully periodic boundary conditions under constant macroscopic stress triaxiality.
