A Preliminary Study on Designing a Composite Materials Hardness Testing Range Expander

Abstract:

This study proposed the preliminary development of a new material hardness testing system. It focuses on a simulation analysis while examining the system’s composite materials hardness testing range expander (CHT-RE). A linear funnel-shaped geometric array structure was designed, using the negative Poisson’s ratio as the geometric structure of the CHT-RE. Conducting a simulation analysis of single-layer and multi-layer compression and tension, this study explored the impacts on the variations of the Poisson’s ratio, which was applied to the composite materials hardness testing design. Initial exploration and analysis were performed, testing the indentation depth, material hardness, relevant properties, and load limits of the CHT-RE, the pressure uniformity of composite materials hardness, and analysis of the nine-point stress distribution.
