There is provided an apparatus (30) for compression testing. The apparatus (30) has a base assembly (60) having an end load element (74) attached to the base assembly (60), the base assembly (60) being rigid. The apparatus (30) has a support assembly (32) attached to the base assembly (60), and having a plurality of window portions (44). The apparatus (30) has a core assembly (46) installed within the support assembly (32), the core assembly (46) being crushable and configured to protect the support assembly (32) and the base assembly (60) from fracture loads (53) generated during compression testing. The base assembly (60), the support assembly (32), and the core assembly (46) together form an apparatus (30) for compression testing of a test specimen (80) having a notch portion (82). The apparatus (30) is configured for use with an optical strain measurement system (120). When the test specimen (80) is installed in the support assembly (32), the test specimen (80) and the notch portion (82) are visible to the optical strain measurement system (120) through the plurality of window portions (44). |
