    Yielded structures

    Hi all I started working on some post yielded structures problem(overloaded during test) and this is new to me. Are there any ways to detect yielding on a surface besides the "visual inspection"? Are there any non destructive testing methods that have been proven to work? I think hardness is...

    Engineering Column Analysis - The Analysis of Compression Members

    I am trying to find a copy of Engineering Column Analysis - The Analysis of Compression Members by William Mccombs for a while now. Any idea how to buy/find a copy of this book? Probably publisher and author are long gone... Any leads or tips much appreciated.

    Floating vs Integral Frames

    Good day, fuselage masters, I have seen couple of really interesting frame designs on few aircraft structural skeletons.I have been thinking about certain fuselage structural elements. What are some of the benefits and cons of integral frames(inner flange attached to skin) vs floating...

    Aerospace Engineering Contracting

    To give some background I have about 10 years of analysis experience in total.I have worked for small companies throughout these years given a lot of responsibility. Currently, contracting seems lucrative due to the rates and OT and dangerous due to easier fireability. Couple of questions to...

    Cold bending and yielding

    Consider this: Couple of T and elbow sections are seamless cold worked tubing(inco625,same filler). T has a hole cut and hole is drawn up to form the collar. How do we account for any of the thinning and residual stresses? Do they matter? If so, is there a good method to account for the...

    Solution 400

    Hi I would like to use the MSC's nonlinear 400 solver in FEMAP. How do you setup this analysis? I can only see the nonlinear static option from the dropdown menu, which I think is the 106 solver. How can I enable the 400 solver?

    Effect of pitch for Composite joints

    I was trying to think of the effect of large pitch distances for single lap composite parts. Normally the pitch distance between the rows is low. What would happen if you were to increase that to lets say 10-15 in, making the joint a very long joint. Would the first row have to be sized for the...

    Landing gear

    I wanted to pick people's brains on if you had the chance to become a dedicated landing gear stress analyst would you? It seems to me that there are not many landing gear "experts" in the industry. And for veteran landing gear analysts: do you regret the choice as it locked you into a very...

    Cquad4 vs Cquadr's

    I have been trying to reason why one should choose one element over the other(pros vs cons). It seems to me that CQUAD4 in Nastran is an half-assed attempt to have a proper shell element as you have to specify the 6th degree of rotation artificially with the K6rot term,whereas Cquadr seems like...

    Large Global Fea model buckling analysis

    Hi, I have been an avid fan of this forum for quite a while. I am currently analyzing and sizing a wing leading edge structure in femap and nx nastran. The structural static analysis is running fine whereas extracting buckling loads is proving to be an issue. Nastran almost requires >150gb...
