Apparatus for high-throughput sequential tensile testing and methods thereof
| DWPI Title: Apparatus used for high-throughout sequential tensile testing, has a sample cartridge that has a first test sample and second test sample, and a cartridge holder is configured to house the attached end of the first and second test samples |
| Abstract: The present invention relates, in part, to an apparatus configured to test a plurality of test samples within a sample cartridge. Such an apparatus can facilitate high-throughput tensile testing of such test samples. Also described herein are methods for using such an apparatus and for testing such test samples. |
| Use: Apparatus used for high-throughout sequential tensile testing. |
| Advantage: As tension is applied, a camera can image the reduced unit of the test sample to monitor changes in structural features, which in turn can provide real-time non-contact stress measurements. The geometry or topology of the test sample can be optimized to reduce overhangs, minimize large bores, and avoid thick layers. Both sets of observations are further bolstered by the radiant energy density results which again show lower radiant energy densities and reduces ductility while higher radiant energy densities can reduce strength and increase variability in mechanical response. |
| Novelty: The apparatus comprises a sample cartridge that has a first test sample and second test sample. Each test sample has a free end and an attached end. A cartridge holder is configured to house the attached end of the first and second test samples. A grip assembly is configured to grasp the free end of the first or second test sample. A stage assembly is configured to move the cartridge holder to a first position and a second position. The first position provides the free end of the first test sample in proximity to the grip assembly. The second position provides the free end of the second test sample in proximity to the grip assembly. |
