Profilometry?Based Inverse Finite Element Method Indentation Plastometry

This is a review of the current state-of-the-art regarding particular approach to extraction (quasistatic) stress–strain relationship metallic sample from an indentation experiment. It based on application relatively high load (kN range) via large spherical indenter (?1 mm radius), followed by measurement indent profile. profile then used as target outcome for inverse finite element method (FEM) modeling test, aimed at converging best fit set parameter values in constitutive plasticity law (true stress–true strain relationship). can be simulate any specified loading configuration, including conventional tensile test. Commercial products are now available which indentation, profilometry, and convergence operations all automated completed within few minutes. The covers various conceptual practical issues involved implementation optimization these procedures, both those related system (experimental FEM simulation) associated with (such anisotropy, inhomogeneities, residual stresses). An attempt made convey impression expected levels reliability also scope obtaining insights that not readily obtainable using other types
