Numerical modeling of strong discontinuities
The paper presents an overview of modern approximation techniques for explicit resolution of strong discontinuities (displacement jumps) that can run arbitrarily across a finite element mesh. Two types of such formulations are covered: (i) elements with embedded discontinuities, which introduce internal degrees of freedom that are eliminated on the element level, and (ii) extended finite elements with additional global degrees of freedom, based on the partition-of-unity concept.
