11. Modeling I#
11.1. Characteristics of modeling#
We use 3D modeling for solid elements with method CONTINUE for the treatment of CONTACT between linear mixed elements and quadratic elements.
11.2. Characteristics of the mesh#
Number of knots: |
227 |
Number of meshes and types: |
16 HEXA20, 25 HEXA8, 32 QUAD8et 50 QUAD4 |
The meshes are incompatible. The contact surfaces are made up of 5 QUAD4 elements in front of 4 QUAD8 elements. The integration diagram used is of the Newton-Cotes type coupled with a technique of subdivision into sub-elements.
