84 Figure 1. Effectiveness Matrix of Standardized Testing Methodologies for Mechanical Material Systems Source: developed by the authors. The proposed matrix represents a two-dimensional model for the comparative analysis of mechanical testing methodologies based on two key criteria: the X-axis (horizontal) – cost and implementation complexity of the methodology (from low to high); the Y-axis (vertical) – effectiveness and informativeness of the obtained results for assessing reliability and strength. Such an approach makes it possible to visually determine the feasibility of applying each methodology depending on the specific engineering or certification objectives. Let us consider in detail the interpretation of the positioning of methodologies within the matrix.
