Determination of the linear thermomechanical parameters of a porous material by virtual tests

The software OOF (Object-Oriented Finite Element Analysis of Real Material Microstructure Working Group) has been developed by NIST (US National Institute of Standards and Technology).

It is used to create a mesh from a picture representing the microstructure of a coating and to simulate mechanical and thermal tests.

The meshing process produces elements of decreasing sizes close to the interfaces between two different materials.

Virtual tensile and shear tests are conducted on the meshed structure to generate the 5 parameters of an anisotropic linear elastic law of behaviour (2 Young's moduli - 2 Poisson's coefficients - 1 shear modulus).

2 different values of the anisotropic coefficient of thermal expansion are also computed by the same model after the simulation of a temperature step.
