7.2. Characteristics of the mesh#
Number of knots: 11, Number of meshes and types: 2 TRIA7
7.3. Tested sizes and results#
The displacement of node \(\mathrm{N01}\) is easily deduced from the reference solution since the deformation is homogeneous. It is tested not at \(A\) but also at point \({A}^{0}({\sigma }^{D}=123.8{\tau }^{D}=76.2)\) on the \(\mathrm{OA}\) route. Cumulative plastic deformation is also tested.
