83 The absence of a systematic approach to comparing the effectiveness of various standardized methodologies complicates the substantiated selection of an optimal testing set for specific materials and application conditions. Practical experience demonstrates that reliance solely on the traditional nature or availability of a given method does not always ensure the acquisition of maximally relevant data. This may result in increased costs, extended development cycles, and the risk of underestimating critical operational factors. In this regard, there is an objective need to develop an effectiveness matrix for standardized testing methodologies of mechanical materials. Such a matrix should provide a comprehensive evaluation of testing methods according to a set of criteria – namely informativeness, accuracy, reproducibility, sensitivity to structural changes, economic feasibility, and implementation complexity – and serve as a tool for their comparative analysis. The formation of such a system will enhance the scientific validity of selecting research methods, optimize resource expenditures, and ensure a closer correspondence between testing results and real operating conditions of materials (Fig. 1).
