A padaptive scheme for overcoming volumetric locking during isochoric plastic deformation
Wells, G N; Sluys, L J (200106)A padaptive scheme is developed in order to overcome volumetric locking in low order finite elements. A special adaptive scheme is used which is based on the partition of unity concept. This allows higher order polynomial ... 
A Précis of Some Recent Developments in Computational Failure Mechanics
De Borst, R; Askes, Harm; Gutiérrez, Miguel A; Remmers, Joris J C; Wells, G N (2002)A concise overview is given of various numerical methods that can be used to analyse localisation and failure in engineering materials. The importance of the cohesivezone approach is emphasised and various ways of ... 
Representations of finite element tensors via automated code generation
Oelgaard, Kristian B; Wells, G N (20090226)We examine aspects of the computation of finite element matrices and vectors which are made possible by automated code generation. Given a variational form in a syntax which resembles standard mathematical notation, the ... 
Simulating discontinuities in a gradientenhanced continuum
Simone, A; Wells, G N; Sluys, L J (2002)A continuumdiscrete model for failure in quasibrittle materials is presented. The continuum is regularised through the introduction of gradient terms into the constitutive model. At the transition to discrete failure, ... 
A study of discontinuous Galerkin methods for thin bending problems
Dung, N T; Wells, G N (2006)Various continuous/discontinuous Galerkin formulations are examined for the analysis of thin plates. These methods rely on weak imposition of continuity of the normal slope across element boundaries. We draw here upon ...
