Your colleague asks you to verify her findings about a new polymer intended for use as a vascular graft. It must be reasonably e

lastic; otherwise, the blood will be constricted and increase its flowrate downstream with each pulse of the heart. She found that the material was sufficiently elastic for use inside the body. After running a tension test, you find that it is too brittle for use. Your colleague reviews your protocol and declares that you have either graduated from Duke or checked your eyelids for light leaks during Dr. Brudno's BME 203 class, because it definitely is adequate. Describe two mistakes you may have made. Put a (1) and (2) before each of your reasons.

Answer:

1.Vascular tube is used for vascular surgery and is very small in size with very small diameter and thickness,thus a little change in environment can also affect there result.

2.When testing for tension in the polymer it is very important to consider the strain rate as the increase in strain  can cause the material to  break.Therefore not only tension test but also strain test is required.
