Torsion mechanical tests are performed to torsionally load devices and materials statically or repetitively to evaluate the torsional strength or fatigue resistance of the device. MDT has performed many torsion tests and has developed a wide range of test configurations and test fixtures for different specimen geometries. Some of the tests and the fixtures we have developed are highlighted below.
In this test devices are either placed in straight mock arteries or mounted directly to the test fixture and subjected to cyclical torsion. The torsion motion creates a dynamic strain in the device which simulates the strains found in vivo. MDT has developed a variety of fixtures for torsional testing.
This test is designed to simulate the device radial fatigue due to squeezing, twisting and stretching of the surrounding vessel in peripheral indications. The test is accelerated to obtain results in less time than physiological rates would allow and is conducted with saline at 37°C.
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.
