PUMA is particularly suitable for fracture mechanics problems. It is well known that such problems pose severe challenges for classical FEM. For example, the solution exhibits a discontinuity across the crack and is singular in the crack tip. In the PUM, these difficulties are rather simple to resolve by the use of available appropriate enrichment functions and suitable solution methods for the resulting systems of equations.
