Abstract
An apparatus and method to test a specimen is disclosed. In one embodiment, the apparatus comprises a housing defining a passage having a length extending along a longitudinal axis, an anvil movable in the passage between a first position and a second position along the longitudinal axis, the anvil comprising a tapered shaft section, an expandable mandrel having an inner surface adapted to fit around a portion of the tapered shaft section and an outer surface adapted to receive a test specimen, and a first block to limit motion of the mandrel. In use, moving the anvil between the first position and the second position causes the mandrel to expand in a circumferential direction, thereby applying a circumferential tension force to the specimen.
