This type of testing arrangement exhibits a plane strain condition and resulted in crack growth rates two orders of magnitude faster than traditional plane stress testing geometries. To validate the DCB specimens, an investigation into the potential cavitation inside the rubber of the DCB specimens was performed.

All of the like-polarity plates are welded together and to the appropriate post. In the case of VRLA cells, some compression of the plate-matte-plate sandwich is exerted to maintain good contact between them.
