A study compared various artifical intelligence techniques for determining Poisson's ratio and Young's modulus. These techniques provide an alternative, less costly method for determining ...

Poisson’s ratio Uniaxial loading Tensile/compressive stress in the x -direction produces tensile/compressive strain in the x -direction, with the stress and strain related through Young’s modulus E: ...

Poisson’s ratio of the film Young’s modulus of the substrate Poisson’s ratio of the substrate The output of the model is the substrate-independent Young’s modulus of the film. Note that although the ...
