4.3 Compression tests provide a standard method of obtaining data for research and development, quality control, acceptance or rejection under specifications, and special purposes. The tests cannot be considered significant for engineering design in applications differing widely from the load-time scale of the standard test.These results show that the diametral compression test method is not appropriate for determining the tensile strength of this spinel and it raises concerns about the applicability of the method .
A diametral compression test involves applying a stress load or force to the point where a material object is split in half (down the diameter of the object). [1] This test indirectly measures the tensile property of a material object, as the molecules of the material are pushed apart in opposite directions, similar to what happens to molecules in a direct tensile strength test.The diametral compression test method on circular disks is used in this study to determine the interlaminar tensile strength of an alumina-based Oxide/Oxide ceramic matrix composite at room temperature, 1200 °C, and at room temperature after being thermally aged for 150 h at 1200 °C.
1. The document analyzes the diametrical compression test through finite element simulations to examine how material properties like plasticity affect stress calculations. 2. Simulations were conducted using linear elastic, elastic-plastic, and porous elastic-plastic models. Results showed significant deviations from analytical solutions when material plasticity was incorporated. 3. . 5.1 Care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materials.

ASTM C1424 determines the compressive strength including stress-strain behavior, under monotonic uniaxial loading of advanced ceramics at ambient temperature. Compressive strength as used in this test method refers to the compressive strength obtained under monotonic uniaxial loading. Compression tests provide information on the strength and deformation of materials .4.2 For a C-ring under diametral compression, the maxi-mum tensile stress occurs at the outer surface. Hence, the C-ring specimen loaded in compression will predominately 1 This test method is under the jurisdiction of ASTM Committee C28 on Advanced Ceramics and is the direct responsibility of Subcommittee C28.04 on Applications.ASTM C496 determines the splitting tensile strength of cylindrical concrete specimens, such as molded cylinders and drilled cores. The splitting tensile strength is typically greater than the direct tensile strength and lower than the flexural strength. ASTM C496 ASTM C496 consists of applying a diametral compressive force along the length of a cylindrical concrete specimen at . Therefore, the proposed diametral compression test method may be an alternative to ASTM C633 (“Standard Test Method for Adhesion or Cohesion Strength of Thermal Spray Coatings”) [43], to quantify the initiation of adhesion failure (or adhesion strength) at the centre of the specimen.
