Are you sure that these values will be same?

Is force required to compress or extend a helical spring is same or different. For example a spring has spring rate of 450 N/mm, so if in compression if 450 N is required to produce 1 mm displacement from free position whether in tension same 450 N force will be required to produce 1 mm...

Thanks But i have seen in some big companies that the Sr FEA engineers r just good at application part ...and not good in basics of maths of FEA... i guess only practical application of FEA is necessary & not its all core maths...its necessary for ppl who r developing those softwares?? isn't...

This books has more mathematical approach .. can u provide me links which teaches basic from pratical point of view ...like there is one book called "Practical Finite Element Analysis" by Nitin Gokhale, Finite to Infinite Publications... Thanks in advance

Thanks again :smile: by the way ,,,whats ur specialisation ?? n where r u from??

can u provide some links to clear basics of FEm from practicality point of view...

now i got it perfectly ...thanks Mech engg...:smile: :smile:

If u are talking about term "Inviscid"...then u are correct.. its means flow is non viscous ,,,that in return means SHEAR STRESSES are minimum and can be neglected

Thanks for help... but can u relate ur answer to interpolation functions?? why elements like octagon, pentagon,etc are not used for 2D meshing(also in solids)?

[/PLAIN] Thanks for such wonderful explanation...

how interpolation functions are affected by choosing higher primitive shapes??

Thanks for reply... Its true...but why those small elements can take any other shape... why only those basic shapes are standardised?

what is exact reason behind choosing basic primitive shapes for elements in FEA? Why it can't be hexagonal, pentagonal, octagonal, etc. in both cases 2D and 3D... Thanks in advance...
