Compression test

Jul 13, 2018In the compression test, a standardized specimen is loaded under compressive stress until it breaks or until a first crack appears. The testing of materials under compressive stress is carried out in the so-called compression test.Standardized round specimens are used, which are much thicker than tensile specimens.The maximum height of the sample is twice the
