Hi,
I am doing a simple problem of a beam fixed at both ends and carrying a uniform distribiuted load, material is steel. The results given by NX are different from the results I get using beam deflection formulas (Theoretical).
In attachments I have attached the beam problem, Beam theory formulas used to calculate deflection and results given by NX.
Since the Moment of Inertia, Modulus of Elasticity values are taken as given by NX itself, and also values of load and beam dimensions are displayed by NX itself , it does not make much sense why both the results are different.
Deflection (Y) given by beam theory is : 1.350E-5 mm and by NX is 2.286E-5 mm which is an error of 69 %.
Whereas the results for Bending stress is coming exactly same from both theory formulas and NX. Can anybody explain why am I getting theses kind of results.
Thanks,
Ashwani Thakur.
