Abstract: The elastic moduli of bulk materials were determined by means of four-point bending test on a self-developed small size four-point bending device. Using a displacement sensor, the method can automatically measure the displacement of the inner support rather than the mild-span of the specimen during loading process. After the calibration of the frame compliance of the device, the elastic moduli of machinable glass ceramic, 6061 Al alloy, c11000 Cu alloy and K9 optical glass were measured using the proposed method and the results coincide with the standard values of the materials. The proposed four-point bending test method is simple and can be used to measure the elastic moduli of bulk materials.

Key words: technology of instrument and meter, elastic modulus, four-point bending, mechanical test, frame compliance
