Grant-in-Aid for Scientific Research on Innovative Areas (Research in a proposed research area)
To understand the interplay of micro-scale defects (such as disclinations and dislocations) and macro-scale phenomena (such as strain-bands and kinks) in metals with mille-feuille structures. Ultimately, to understand the interplay of disclinations and kinks on materials strengthening.
FY22. Completed the micro-scale modeling of finite systems of disclination and dislocations, including disclination dipoles, which are proxy for kinks. Clarified the influence of geometrical parameters of the system on energy scalings. Computed effective energies with Gamma-convergence (1 paper published).Developed computer programs and run simulations for tensile tests of metals in various crystal symmetries. Clarified qualitatively (in terms of phase diagrams) and quantitatively (in terms of bifurcation parameters) the dependence of kink morphologies on the symmetry of the lattice (square vs. hexagonal) and of the domain aspect ratio (1 paper in preparation). Additionally, developed a numerical platform blending Density Functional Theory, Machine Learning and Genetic Algorithms to optimize the topological and geometrical properties of functional molecules (1 paper published). This platform can find an application in the design of better materials (including metal alloys) for specific applications by tailoring the pattern of lattice defects.
