Method and apparatus for determining the true stress and true strain behavior of a ductile polymer |
摘要 |
A small punch test apparatus is used to determine true stress and true strain in a ductile polymeric material as it undergoes deformation by the punch head. The information gathered can be used comparatively to assess the acceptability of a body implant subjected to sterilization against similar information obtained on another implant of the same polymer already known to be acceptable.
