MIL-HDBK-5H Specimen Size
MIL-HDBK-5H Specimen Size
(OP)
Hello,
I am trying to extract the percentage of elongation to put into Abaqus for a simulation of plastic failure.
Now I have found a good site (see below) which allows me to extract accurate values from the graphs within MIL-HDBK-5H however this graph plots (Stress vs Strain (in./in.)).
http://ww 0.knovel.c om/knovel2 /Show_Grap h_Flash.js p?SetID=48 13230& BookID=754 &Datat ype=6false
However, this strain value is useless without having the original specimen/sample size to give the percentages I require.
Now I've trawled through the MIL spec and for the life of me I can't find where is says the test sizes for 'Sheet' aluminium.
Can anyone shed any light on where I would find this sample size data as so far this sheet could be 2'x2' or 8'x8'?
Appreciate any assistance,
Regards,
Rob

RE: MIL-HDBK-5H Specimen Size
From MIL-HDBK-5H:
1.4.3.5 Elongation and Reduction of Area — Elongation and reduction of area are measured in accordance with specification ASTM E 8.
1.4.4.6 Elongation (e) — An additional property that is determined from the tensile test is elongation, which is a measure of ductility. Elongation is the increase in gage length, measured after fracture of the tensile specimen within the gage length, expressed as a percentage of the original gage length. Elongation is usually measured in 2 inches for rectangular tensile specimens and in 4D for round specimens, except welded specimens. See applicable material specification for specified gage length.

Thanks for that, so the original gage length is 2 inches?
Seems rather small for a test specimen or is it me?
Thanks for your help, eyesight is not what it was thats for sure!
