Static tests were studied for the determination of mechanical properties of brittle materials. Specimens of brittle materials, represented by cermets having five different compositions, were subjected to tensile, compressive, torsional, transverse, and impact tests. The designs of specimens sand apparatus, suttability of the tests to the materials, refinements in test procedures, and the variability of results and their correlation were studied. The elastic properties were obtained from tensile, compressive, snd transverse tests, and the modulus of rigidity calculated from the results of these tests sgreed with that from the torsional tests. Tensile strength was obtained from the tensile, torsional, and trsnsverse tests on specimens of comparable sizes in accordance with a limiting tensile strsin. Shear strengths were obtained in the compressive tests. The correlation of impact values with mechanical properties was unsatisfactory.
