The integrated singular basis function method for the stick‐slip and the die‐swell problems
(1991)We further develop a new singular finite element method, the integrated singular basis function method (ISBFM), for the solution of Newtonian flow problems with stress singularities. The ISBFM is based on the direct ...

Newtonian and non-Newtonian flow in a channel obstructed by an antisymmetric array of cylinders
(1991)Consideration is given to the flow of Newtonian and non-Newtonian elastic liquids in a channel obstructed by an antisymmetric array of cylinders. Experiments are carried out on Newtonian maltose-syrup/water mixtures and a ...

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 ...
