A singular finite element for Stokes flow: The stick–slip problem
(1989)Abrupt changes in boundary conditions in viscous flow problems give rise to stress singularities. Ordinary finite element methods account effectively for the global solution but perform poorly near the singularity. In this ...

Singular finite elements for the sudden‐expansion and the die‐swell problems
(1990)The singular finite element method is used to solve the sudden‐expansion and the die‐swell problems in order to improve the accuracy of the solution in the vicinity of the singularity and to speed up the convergence. The ...
