3. Modeling A#

3.1. Characteristics of modeling#

We consider a rectangular plate modelled by an incompressible element QUAD8: miplqu8. The two cases are studied: the first with the two amplified loads, the second with the amplified horizontal pressure and the constant vertical.

3.2. Characteristics of the mesh#

Number of knots: 8

Number of meshes and types: 1 mesh of type QUAD8, incompressible finite element.
