Original Abstract

There is a research project in IAM Brno, Ltd. The aim of this project is to develop a methodology for evaluation of mechanical properties using NDT methods. Methodology is developed focusing to evaluating the mechanical properties of the heterogeneous weld structure. The material mechanical properties are determined by conducting a nondestructive instrumented hardness testing according to Vickers. Then the developed methodology for the basic mechanical properties determining is based on the inverse FEM modeling principle of instrumented hardness testing when the indentation curve and the measured surface imprint are the output of indentation. The processing of these outputs from the experimental hardness testing processed data (the corresponding values from indentation curve and measured surface) are not always corresponding. Then these differences affect the accuracy of the developed methodology, because comparing the outputs of the experimental instrumented hardness test and modeled hardness test using FEM is achieved of the basic material mechanical properties.
