Inclined Embedded Elliptic Crack

Non-planar growth of an inclined embedded elliptic crack

This example shows crack growth of an inclined embedded elliptic crack in square section test specimen under tension - initially a mixed mode defect but quickly turning to mode I. As this is an internal defect some of the images below show cut-aways to reveal part of the mesh and the full crack surface. The animations also include a zoom-out to enable the initial and final crack sizes to be viewed.
