3. Modeling A#

3.1. Characteristics of modeling#

This modeling is based on linear meshing. The 9 surface meshes (QUAD4) of each plate are affected by the DKT model.

3.2. Calculations and loads#

Two calculations are carried out on each plate of the mesh. Calculation loads are detailed on group COQ_X. Then simply replace \(X\) by \(Y\) and then \(Z\) to get the loads of the other calculations.

3.2.1. Reference calculation, pre-deformation defined by value#

In the reference calculation, the following pre-deformation values are assigned:

	G1X	G2X	G3X
EPXX	1E-3	2E-3	3E-3	3E-3
EPYY	2E-3	4E-3	6E-3
EPXY	3E-3	6E-3	9E-3	9E-3
KXX	4E-3	8E-3	12E-3
KYY	5E-3	10E-3	15E-3	15E-3
KXY	6E-3	12E-3	18E-3	18E-3

The dependence on time is taken into account by adding an « identity » multiplier function to the load.

3.2.2. Second calculation, pre-deformation defined by function#

The following pre-deformation load is affected on all the cells of plate COQ_X:

EPXX	\(\mathrm{1E-3.}\mathit{escalier}(X)\mathrm{.}\mathit{INST}\)
EPYY	\(\mathrm{2E-3.}\mathit{escalier}(X)\mathrm{.}\mathit{INST}\)
EPXY	\(\mathrm{3E-3.}\mathit{escalier}(X)\mathrm{.}\mathit{INST}\)
KXX	\(\mathrm{4E-3.}\mathit{escalier}(X)\mathrm{.}\mathit{INST}\)
KYY	\(\mathrm{5E-3.}\mathit{escalier}(X)\mathrm{.}\mathit{INST}\)
KXY	\(\mathrm{6E-3.}\mathit{escalier}(X)\mathrm{.}\mathit{INST}\)
