This article puts its focus on stress singularities and stress concentrations in Finite Element Analysis. What are they? When do they pose for concern? How should we, as FE analysts, deal with them?
The Finite Element Analysis (FEA), also called the Finite Element Method (FEM), is a numerical technique to find numerical solutions to partial differential or integral equations of field problems. In stress analysis this field is the displacement field whereas in thermal analysis it is the temperature and in fluid flow it is the velocity potential function, and so on.
