Comparison of Ceramic Uniaxial Compression Specimens through Detailed Finite Element Modelling
Abstract
Mechanical properties of advanced structural materials are determined through physical testing. In the area of high strength ceramics, routine testing includes techniques for measuring compressive strength. Successful and efficient characterization of compressive strength and other properties allows the design engineer to exploit the maximum structural potential for these advanced materials. This report details comparisons made between two proposed dumbbell- shaped, uniaxial ceramic compression specimens. Comparisons were made for alumina (aluminum oxides) material through detailed finite element modeling. Differences in stress distributions resulting from both geometries were then applied to experimentally obtained strength values to determine if these values were representative of the same statistical population.
