Abstract
A testing apparatus for applying a test load to a specimen, comprises a cradle and a test bed supported on the cradle. The test bed has a chamber which receives a specimen and is hermetically sealed with the specimen received inside. There is a vacuum source in communication with the chamber. The vacuum source provides vacuum pressure to the chamber, thereby applying a uniform load to the specimen.
Claims11
A testing apparatus for applying a test load to a specimen, the testing apparatus comprising:
- a cradle;
- a test bed supported on the cradle, the test bed having a bottom and a frame extending about the bottom to define a cavity, the cavity receiving a specimen and being covered by a flexible sheet so as to hermetically seal the specimen inside;
- a pair of rails extending along the bottom of the test bed and on opposite sides thereof, each of the rails having a pair of support brackets which are each movable along a length of said rail such that the support brackets can support specimens of different lengths;
- a dampening mechanism coupling the test bed to the cradle;
- and
- a vacuum source in communication with the test bed, the vacuum source providing vacuum pressure to the test bed, wherein the vacuum pressure applies a uniform load to the specimen and the dampening mechanism dampens reaction forces from a sudden release of the vacuum pressure when the specimen fails under the load.
