Oh, and to answer NickE... hmm can you please elaborate on the equation? I thought the AREA mattered, so I would get 0.018 N/mm^2 ? How the thickness fits in and gives you 180 N/mm^2 (it's perfectly logical, but then I would expect mm^3)?
The 25mm is reported just to denote the methodology, i.e. the fact that a strip of 25mm wide was used. I did not give you the elongation because I did not ask about it. But if I have, let's say, a 40mm elongation at break, then that would be 40*100/200 = 20% El@B.
Hello!
I have been completely stumped by the tensile strength unit N/mm2 ! I work in the pressure sensitive adhesives industry, and I normally measure the tensile strength of a film (Polypropylene, PVC, masking tape etc) following the AFERA method 5004, i.e. a strip of 25mm x 200 mm is...
