Well really the match here is a result of the fact that the problem is over-driven. The notch creates a highly localized stress field.Ozzie_Isaac said:
Out of curiosity, how do you control the surface finish on your specimens? You theoretical data matches the empirical data so closely, you must be doing a pretty spectacular job of controlling the variables, surface finish, in my mind, being one of the critical ones.JohnInCarolina said:

The green surface is our best guess of what the strength surface for this material could be. The blue, red, and yellow lines correspond to an analysis of three different specimens of a notched Aluminum material. The points where they end are where the specimens all failed. The fact that they just touch the surface seems to indicate that failure is being governed by strength in this case, as opposed to energetics.
We use FEA for the calculations, and compare results to experiments conducted at a lab in Tel Aviv. I actually teach a couple of different graduate courses on linear and non-linear FEA here at Duke.
They may do something in the lab at Tel Aviv to polish the surface within the notch, I’m not sure."I've made a note never to piss you two off." - Stike -

No, he’s asking why there doesn’t appear to be much of a stochastic element to the data, because with strength there typically is.nolaegghead said:

Our FEA was usually run with worst case scenario specs. Steel manufacturers had a range of what they could produce given a certain material callout. We ran stimulation at lowest grade.
Forming thru a notch can prove problematic, but keeping trim details with 3d shape on them sharp is very expensive.
If we started having problems after hard tooling was made, we would send out the material for analysis to make sure it was what it was supposed to be.Large, Medium, MiniMax, & 22, and 36" Blackstone

This exactly, the fact that the three data points shown land on the theoretical curve is extremely impressive. From the material properties of the specimen to the quality of machining is impressive. These data sets usually seem to come with all the caveats and explanations. Even the best sets have a noticable distribution.JohnInCarolina said:

We just built a new arena for our AHL team. They are supposed to open the building for hockey the first week of April. Pretty excited to go watch a game there.FarmingPhD said:Minor league hockeyLas Vegas, NV -
Kids had a blast, forgot how much action there is in hockey which really keeps the kids attention. The company my wife’s sister and B-I-L work for owns the team and snagged free tickets. Staying at a hotel north of Naples, per @saluki2007 I’ve been paying attention to vehicles down here. They have not disappointed, BMW i8 roadster, Bentleys, corvettes are common, and stuff I don’t know what it is other than expensive.Battleborn said:
