The emerging field of “Materials by Design” aims to identify and process materials comprising specific microstructures that are predicted to meet or exceed multiple performance criterion stipulated by the designer. It is in this context that a new microstructure design framework called Microstructure Sensitive Design (MSD) was recently proposed[1]. This paper discusses the MSD framework applied to microstructure (crystallographic texture) optimization for an orthotropic plate with a central circular hole and subjected to in-plane uniaxial tension. Finite element methods were used to estimate the applied load at yield for the polycrystalline nickel. The optimal polycrystalline texture was found to be able to sustain a far-field stress (away from the hole) of 1.28τCRSS, where τCRSS denotes the critical resolved shear stress (at the single crystal level). This solution was validated by direct comparison with finite element simulations that employed a Taylor-type polycrystal constitutive model at each integration point.
