5. C modeling#

5.1. Characteristics of modeling#

The crack is modelled using the X- FEM method. We use C_ PLAN modeling and the CALC_G_XFEM operator.

5.2. Characteristics of the mesh#

The mesh contains 96000 elements of type QUAD4.

5.3. Tested sizes and results#

Dynamic stress intensity factors \({K}_{I}(t)\) and \({K}_{\mathit{II}}(t)\) to \(t\mathrm{=}2.E\mathrm{-}3\mathit{sec}\) are tested.
