• Yes, prop_design, such a simple geometry but I'm still learning: In order to see which elements are actually in contact, I looked at the compressive stresses on the inside of the hole. Below is the plot for sigma-3 and indeed the bottom half is in…

• VMH - I recomputed my version with just the bottom half and a similar color scale so that our results are quite similar despite this model only has 672 hex20 elements. But notice how in both of our results, the strap has deformed _away_ from the "p…

• Since the upper surface of the pin hole pulls away from the pin, a more appropriate boundary condition is the compression only BC applied completely around inner surface. Below is a png of the stresses for 1280 hex20 elements with max stresses at th…

• Very nice: I found the "coil spring" and the recent VMH videos; are there more?

• I'm also interested in nonlinear stress-strain curves for light airplane design. Many parts in small airplanes (LSA, homebuilt, etc) are cold-formed from sheet, bar, tube stock in such metals as aluminum 6061, steel 4130, etc. After yielding, the pa…

• Oops, just discovered the "visible" option by right-clicking component - marvelous.

• Here are the two text files for pressure loads which my math program outputs in liml format for the above test case. These are edited in WordPad and must be saved in unicode format to handle superscripted units. My math program kept outer quotation …
