The final methodology will focus on evaluating the mechanical properties of the heterogeneous weld structure. The mechanical properties are determined by conducting NDT instrumented Vickers hardness test. The developed methodology for the basic mechanical properties determining is based on the inverse FEM modeling of instrumented hardness test and the indentation curve and the measured surface imprint are the output of indentation. The outputs from the experimental hardness test (the corresponding values from indentation curve and measured surface) are not always corresponding. These differences affect the accuracy of the developed methodology, because it is achieved of the basic material mechanical properties by comparing the outputs of the experimental instrumented hardness test and modeled hardness test using FEM.
