Discontinuous element approximation for dynamic fracture

Journal article

A new set of numerical methods for predictive modeling of crack propagation on aircraft structures based on discontinuous interpolation is introduced. These methods solve many shortcomings and limitations of classical FEMs, in particular in terms of accuracy and stability of the numerical approximation. The combination of these methods with appropriate adaptive local re-meshing can circumvent the unreliability and high mesh-dependency of classical approaches, and can effectively model fracture onset and propagation. Some results are presented on the simulation of fracture of ductile and brittle materials.
