摘要
Multi-dimensional finite element modelings of instrumented sharp indentation on materials with cubic symmetry are conducted. A novel reverse analysis algorithm for identifying elastoplastic properties is established for the cubic material, while the anisotropy of the material is determined by indentations on distinct orientations. Influences of elastic anisotropy and anisotropic yielding behavior are considered with the help of three-dimensional computations. Sensitivity analysis confirms the accuracy and robustness of the new method. The obtained results are compared and verified with experimental data of a nickel-base single crystal alloy.
