The results of the flexure test show the material behavior, in particular, near the surface of the specimen. The deflections measured are approximately four times greater than the extensions in a tensile test. ZwickRoell testing machines can compensate for deformation of the load frame, force sensor, and flexure test tool using the testXpert software. Measurement is sufficiently accurate via the testing machine's crosshead displacement transducer. Operating the machine is simple, especially for quality control purposes. If a high degree of reproducibility is required, we recommend using an extensometer that facilitates load-free deflection under the specimen. ZwickRoell offers sensor arms for flexure tests that can be used with the automatic extensometers, makroXtens and multiXtens, instead of tensile sensor arms.
