    How to create a surface field in the solid part?

    No success here, LWolf. It sounds like an easy task, but I am not have success in doing it: draw a shape, make a surface of this shape, associate this shape to the solid and modify the thickness on this shape area (in my case reduce the thickness of the solid in that specific area). How can it...

    Fuselage Hoop Stress Calculation

    Thanks for your feedback rb1957! Yes, indeed non circular fuselages cross sections promotes secondary effects, but the uncertainty itself is specifically about the theoretical hoop stress (P * r / t). In a circular fuselage there is no issues...r is the radius...case closed. But in a non...

    Fuselage Hoop Stress Calculation

    We had a discussion in our group on how do the hoop stresses are calculated in a fuselage section composed of different radii (non circular shape). Do you use the biggest radius (being conservative)? Do you use the local radius for a given panel? Do you use the opposite radius of the panel you...

    Connection Analysis - Fastener Loads on Fasteners of Different Sizes

    Hello, In a bolt group one of the bolts are oversized. How do you calculate the new bolt load? I heard discussions about it and anyone came with a conclusion. Some choose to go with Huth approach, some goes to (D2 / D1) and some with (D2 / D1)^2 approach. Which one do you agree is the best...
