Does anyone know what math formulas are being used by Mecahnica to calcualte the function of a fastener? The PTC web site has a How2 paper, but it only says they are a spring element. We have some people who want to know the math formulas so we can varify the calculated results with actual test results. Also, we can take the fornulas into Excel and calculate results in a few seconds instead of the 2 hours it takes to do the setup and calculations in Mechanica.
