Estimation of mechanical properties of polycrystalline microcomponents

This work deals with the elastic properties of polycrystalline microcomponents made of Gold. Finite element calculations with ABAQUS are carried out so as to identify the characteristic parameters of the distribution of Young's modulus. In the finite element model, the microstructure of the microspecimens is represented by a periodic Voronoi tessellation and a uniform distribution of single crystal orientations on SO(3). Experimental values of the mean value and the standard deviation of Young's modulus are compared to predictions of finite element simulations and to the Voigt and the Reuss bound as well as the Hashin-Shtrikman bounds.
