Hi EdStainless, OK, thanks for pointing out. I think the keyword I was struggling to find is "Bulk Material". So, a standard test should reveal the intrisic properties of the as-built "bulk material". 3D printed parts are expensive, so I don't think we are planning to test more than 5 samples.
If the anomaly were caused by shifting extensometer (due to rough surfaces), then shouldn't this be consistent throughout the curve?
I should have clarified that the 2 pictures are not related. The coupons that that were tested have been machined as per test requirements, so there were no...
Hi,
I've just completed some tensile testing of 3D Printed Aluminium coupons, and the results look suspect. Can anyone shed some light as to what could have caused the initial anomaly in the Stress-Strain diagram?
A second question I have is that I am looking to tensile test coupons in the...
