Bending mechanical tests are performed to load devices and materials statically or repetitively in bending to evaluate the bending strength or fatigue resistance of the device to bending. MDT has performed many bending tests and has developed a wide range of bend test for different specimen geometries. Some of the tests and the fixtures we have developed are highlighted below.
The test demonstrates the device integrity when subjected to bending for an appropriate post-implantation time period. Fatigue tests are conducted for a minimum of 10 years post-implantation while feasibility or strength characterization tests may be shorter.
Bend Test Fixtures are used to convert the axial motion or rotary motion of the ELF and Instron fatigue testers into various forms of bending motion or motions that combine bending and other motions. MDT has developed many types of fixtures for this purpose and the various designs center on the primary purpose of the test. The attached list of fixtures include descriptions of the types of bending performed.
If you don't see the torsion test you are looking for chances are we have already performed the test but have not listed it here. Contact us with your testing requirements and we will provide an estimate for creating the torsion test you are looking for.
