Abstract | The present work proposes a novel method for the simulation of crack propagation
in brittle elastic materials that combines two of the most popular approaches
in literature. A large scale displacement solution is obtained with the
well known extended finite elements method (XFEM), while propagation is governed
by the solution of a local phase field problem at the tip scale. The method,
which we will refer to as Xfield, is here introduced and tested in 2D under mixed
modes I and II loads. The main features and the capability of the Xfield to efficiently
simulate crack propagation are shown in some numerical tests. |
