Super helpful training vid, thankyou so much! I was plunged into the deep end with overlap shear testing last year, and even now i dont feel confident making methods. This tutorial makes me want to jump right in and test test test! Thankyou, much love from the UK x
We don't have an 8801 here, so I'm not sure about its specifics. But if you're using Bluehill Universal, you'll likely be doing either a creep method or a test profiler method. Creep methods are best for pulling (or pushing) to a certain displacement (or force) then holding the sample there for a set amount of time. This will measure the amount of displacement or force relaxation in the sample over time. A test profiler method is much more versatile, and would allow you to do things like cycles of tension, holds, and compression. We recently completed a test that ran 10,000 cycles of compression. There are some software limitations (we were unable to track the displacement at each of the 10,000 maximum forces), but we used a secondary software to do the final analysis on the actual fatigue over the multiple cycles. Hope this helps somewhat!
Can you clarify - what do you mean by "adapters?" And for the deflectometer, are you asking about an extensometer (such as for tension/ compression tests) or a deflectometer (such as for flexture tests? Depending on the model of your adapters or deflectometer, I can try to assist.
Are you interested in setting up a method, or installing the fixture? We use the www.instron.com/en/products/testing-accessories/flexure-fixtures/three-point-bend-test-fixtures?region=Global%20Site fixture in our lab; is that the same one you're interested in learning about?
