validity limit for elastic deflection equation due to simple bending
validity limit for elastic deflection equation due to simple bending
(OP)
Hi all,
I would like to know if the elastic deflection equation for transverse bending loadings : dy^2/dx^2=Mf(x)/EI is valid for any beam dimensions.
The Beer Handbook Mechanics of Materials says it is valid for any cross section. However, is it valid for thin-walled beams? Dimensions like L=1 m , h=0.3 m, b=0.2 m and t=0.002 loaded with a concentrated load at midspan??? I could not find this information anywhere. I looked for it on a lot of books I have.
Thanks,
Best regards,
Mark
