The numerical computation of singular minimizers in two-dimensional elasticity
We use a spectral-collocation method for the computation of singular minimizers in two-dimensional elasticity. In particular, we are interested in computing cavitating solutions (those that open a hole at the center) and determining whether or not they are globally stable in the energy sense. We describe the spectral collocation method which is used in conjunction with a Richardson extrapolation iteration and discuss various aspects related to the convergence of the method.
