Abstract
Since the mid of 1990’s a lot of work has been done around the concept of the Partition of Unity Method (PUM), leading to a great number of variant of this method, above all specialized on the treatment of local discontinuities or local nonlinearities. In effects, the combination of the PUM method with the Finite Element Method (FEM) led to the so-called PUFEM, offering a concrete opportunity for the solution accuracy improvement with respect to the standard FEM analysis.
