beam deflection for axial load
beam deflection for axial load
(OP)
Hi everyone, I am working on a compressive machining fixture that will support a copper rod with a through hole along the center. The boundary conditions I am assuming are fixed-fixed since the fixture will constrain either end of the rod preventing it from experiencing any rotation or pivoting. The issue I am having is that I want to calculate the vertical deflection of the rod as a function of distance from either end, assuming an axial compressive load, but I cannot seem to find any kind of handbook solution. Would I have to solve the diff equation for the elastic curve in order to get the maximum vertical deflection along the rod? This seems textbook for shear loads or transverse loads, but for axial loads I cannot seem to find the maximum vertical deflection. Thanks!

an ideal (euler) column doesn't deflect out of straight untill it spontaneously buckles.
a non-ideal column (with eccentric load, end moments, non-straight, etc) will have a bending moment due to the imperfections which'll allow you to calculate deflections (double integration)

Can you advise on this or provide a sketch for people to understand your problem.

you're clamping end-to-end ... so parallelism of the ends (and real world lack thereof) would affect your column.
