Bend fixtures are used with universal testing machines in order to determine the flexural properties, including flexural (bend) strength and flexural strain, of materials. ADMET bend fixtures are configured for 3-point and 4-point bend testing and are available in a variety of force capacities, support types, and span lengths.
Model selection is often based on the size of the test specimen, expected forces, and the test method followed. Contact us to discuss your testing needs and we’ll help you find the right bend fixture for your application. Read more about bend testing and equipment in our Bend Testing Equipment Guide.
