Aníbal Sánchez Numa posted a new comment: Hello, I used now a very low stressUpdateInterval and it's much better, the stress changes from the very second point, so I could now use the first slope (between the first and second point) or I could use (as you suggested) the linear regression. From my point of view the linear regression is better since I would be calculating an approximate slope from a long part of the curve and if I calculate the first derivative it would be in just one point, so I prefer the linear regression but which are the "right points"?? I plotted the curve using Excel and it makes some "jumps" in some points (I don't know why) so I took just the initial part where I see a pretty well defined ascending slope and got the slope from the regression. Do you think that would be right?? It's very important for my research to get an accurate Young modulus since I'm trying to relate it to the material's equivalent...
