Abstract
A system for strain testing employs an ink aspiration system adapted to apply a stochastic ink pattern. The stochastic pattern is applied to a test article and a test fixture receives the test article. A digital image correlation (DIC) imaging and calculation system is positioned relative to the test article to image the stochastic ink pattern.
Claims20
A method for strain testing comprising:
- creating a stochastic pattern with ink aspirated from a source and spayed on an article to be tested;
- performing a strain test on the article inducing a strain in the article witrh a resulting change in the stochastic pattern of the ink;
- and,
- measuring the strain using a digital image correlation (DIC) imaging and calculation system viewing the stochastic pattern.
