Three-Point Bending Device for flexure testing of soft tissues
2009 IEEE 35th Annual Northeast Bioengineering Conference, 2009This 3-Point Bending Device is intended to provide the user with a novel tool used to obtain material property information for biological tissues. Specifically, the device is intended to provide the user with the stress-strain relationship of the tested tissue in the low-strain region (≪5% strain) and provide the location of the neutral axis.

Optimization of the three-point bend test for fracture energy measurement
Journal of Materials Science, 1977Of the various methods for measuring the fracture energy of a material, the three-point slow bend test has the merit of being simple and straightforward to execute. It can only be expected to give valid results, however, when the crack propagates quasi-statically.

Finite element modeling of the three-point bend impact test
Computers & Structures, 1993Abstract A dynamic finite element program has been applied to the analysis of the three-point bend impact specimen. First, the behavior of an unsupported specimen struck at its center was modeled. From this it was predicted that the best striker force response in an impact test would be obtained with an overhang at each end of 22% of the total length.

Influence of bending rotations on three and four-point bend end notched flexure tests
Engineering Fracture Mechanics, 2008Abstract It has been experimentally observed that mode II critical energy release rate (GIIC) values determined by four-point end notched flexure test and three-point end notched flexure test are different for the same material. At the present work correction factors related to bending rotations are introduced to explain the differences between ...

Impact Three-Point Bend Testing for Notched and Precracked Specimens
Journal of Testing and Evaluation, 1978Abstract Testing and data analysis procedures developed from a recently completed fracture toughness testing program on ferritic nuclear pressure vessel steels are presented. These procedures describe the measurement of dynamic fracture toughness at stress intensification rates near 105 MPa√m/s using instrumented impact testing of three ...
