Analysis of a finite element formulation for modelling phase separation
Wells, G N; Garikipati, Krishna (Springer, 2007)The CahnHilliard equation is of importance in materials science and a range of other fields. It represents a diffuse interface model for simulating the evolution of phase separation in solids and fluids, and is a nonlinear ... 
A $C^0$ discontinuous Galerkin formulation for thin shells
Dung, N T; Wells, G N (2007)This paper presents a C 0 discontinuous Galerkin formulation for the simulation of thin shells. The method is based on Koiter’s shell model and allows finite element solutions to be obtained by using standard $C^0$ Lagrange ... 
Computer code in support of the manuscript "Phase field model for coupled displacive and diffusive microstructural processes under thermal loading"
Wells, G N; Maraldi, Mirko (2011)Supporting material for the article: Maraldi, M., Wells, G. N., and Molari, L. (2011). Phase field model for coupled displacive and diffusive microstructural processes under thermal loading. Journal of the Mechanics and ... 
Discontinuous modelling of strain localisation and failure
Wells, G N (20010612)The computational simulation of failure in solids poses many challenges. A proper understanding of how structures respond under loading, both before and past the peak load, is important for safe and economical constructions. ... 
DOLFIN: Automated Finite Element Computing
Logg, Anders; Wells, G N (2009)We describe here a library aimed at automating the solution of partial differential equations using the finite element method. By employing novel techniques for automated code generation, the library combines a high level ... 
An interface element based on the partition of unity
Simone, A; Remmers, Joris J C; Wells, G N (Delft University of Technology, 2001)An alternative interface ﬁnite element is developed. By using the partition of unity property of ﬁnite element shape functions, discontinuous shape functions are added to the standard ﬁnite element basis. The interface ... 
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 ...
