Abstract
A system which cyclically applies and reduces a load on a test specimen to thereby subject the test specimen to tensile testing, wherein the system comprises a fluidic mechanical muscle that contracts and extends in length to cyclically apply and reduce the load. This system can use an apparatus comprising: (a) a frame; (b) a load adjusting section associated with the frame and having a fluidic mechanical muscle that contracts and extends in length to cyclically apply and reduce a load; (c) a load train section associated with the frame for subjecting a test specimen to the load; and (d) a lever arm associated with the frame and having load train end adjacent and connected or attached to or otherwise associated with the load train section and a load adjusting end adjacent to and connected or attached to or otherwise associated with the load adjusting section, the lever arm being configured to apply and reduce the load from the loading adjusting section to the load train section. The system and apparatus can be used in a method comprising the following steps: (a) providing a test specimen; and (b) cyclically applying and reducing a load on the test specimen to thereby subject the test specimen to tensile testing, wherein the cyclical application and reduction of the load is caused by the contraction and extension of a fluidic mechanical muscle associated with the load. The system or apparatus can also comprise a mechanism for decoupling at least a portion of the load from the test specimen when the load is reduced.
