2. Modeling A: meshed crack in dimension 2#
In this modeling, we consider the structure in \(\mathrm{2D}\). The classical finite element method is used. This modeling is used as a reference for the future.
2.1. Characteristics of the mesh#
The structure is modelled by a regular mesh composed of \(100\mathrm{\times }100\) QUAD8, respectively along the axes \(x\), \(y\). The crack is meshed.
2.2. Tested sizes and results#
We test the values of the following displacement \(X\) and \(Y\) of the end point “PTEXTR” with coordinates \((1;1)\).
We also test the value of the stress intensity factor \({K}_{I}\) given by CALC_G, option K, as well as that given by the \({K}_{I}\) of POST_K1_K2_K3 [bib2].
Finally, we test the \(G\) given by CALC_G, option G.
All of these tests are non-regression tests.
The values obtained for DX, DY, G and the value of K1 obtained serve as reference values for the following models.
