It’s clear that there are a lot of issues regarding outsourcing. Personally, outsourcing work mainly benefits rich folks. (Sure, any person reading this would see the writer as a person who probably lost his job or someone who hates outsourcing). No I do not. In fact I love the idea of a global...
i earned my BSME from San Diego State Univ and working full time. i am considering taking online classes (for masters).
the internet really revolutionized a lot of things. i think online degrees should be recognized like the degrees earned from "brick & mortar" universities. its only a matter...
just adding my 2 cents,
as you already know, stress depends on the area and force. if you are familiar with the geomtry of your fem, then check the output force. this way you actually see the diffenece between the two loads (bending or shear).
when comparing shear and bending its probably...
I'm trying to model a tapered bar:

I've tried downloading the file twice and I keep getting an error. It says "I/O error timeout!" and when I check the file its about 73 MB and its corrupt. What could be the problem?
Is anyone having thesame problem too? Is there any other link to download the file from?
Thanks for reading...
hi to all, i am currently trying to convert an FEM modeled using 'inches' (no loads - just elements) to 'meters'. i did this once but i forgot, all i remember is that i need a multiplier. i cant remember where the function is in patran.
hope you can help. thanks for reading...
yes. we are currently studying a structure that was giving us some weird numbers (bending and deformation) when ran using SOL 101 (Nastran). were now runnig it using SOL 106 (nonlinear-MSC.Nastran) due to the membrane effect that jetmaker & jagad5 brought up. so far were not converging only up...
For allowable damage, you would usually be concerned with areas where likely damage would occur. i.e. traffic areas for the maintenance personnel (scratching the panels or frames). In my experience we have two types of analysis, one is for flyby and the other is for allowable damage.
Allowable...
Thanks for all the replies. I just got back from vacation. I didn't expect a reply that quick and that many.
I gather 1/20 is a good rule of thumb (thanks fsi). I agree with corus about the shell in that ‘stress distribution through the thickness (roughly) linear’ (with good engineering...
In shell analysis (i.e. buckling, etc...), I've always wondered how thin is a thin plate. What is considered a thin plate? What is the definition of a thin plate? This is something I missed asking my profesors back in college. Thanks.
just to add, a negative principal stress does not necessarily mean the membrane will buckle. it is ,as pointed out by corus & freebody, dependent on geometry and boundary conditions. bending, compressive (in x or y directions), and shear stresses or two or more combination of theses stresses...
been in the industry for 2 yrs now and all i can say is that 'right now,' MSC.Nastran & MSC.Patran is a good combo. Although its more expensive than NE, you get the advantage of having the leaders in the Nastran side of FEMs. Documentation is great, they have a support website that can get you...
