Abstract
A strain testing apparatus which places tensile forces on a sheet, a film, or the like samples in at least two axes and generally in a radial direction. The multi-axial strain testing apparatus comprises a clamping assembly having at least two clamping members, and a sample securing portion arranged in a substantially radial manner about a point. The multi-axial strain testing apparatus can advantageously be employed to test crack growth propagation and flex fatigue in rubber polymer and elastomer samples.
