v7.03.106 HPLV106 — Homogenized parameters of a hexagonal cell glass resin-fiber composite

Summary:

The objective of this test is to calculate the equivalent thermoelastic properties of a resin-glass fiber composite with a hexagonal step. The basic materials of the components are isotropic.

This test serves as a check for command CALC_MATE_HOMO by comparing the results to the values presented in the mechanics course (Amphi EDF Lab) by Professor Jean-Jacques MARIGO.

In order to use the CALC_MATE_HOMO command, we do the exercise of determining a square step pattern in the hexagonal step (in order to have a parallelepiped base cell) and we only model the positive octant.

The 3 models correspond to 3 different fiber/resin ratios (0.2; 0.4; 0.6).
