Can we demonstrate with a simple example the structural response change from axial deformation to bending, in buckling problems?

Most often when a column is under axial load, we say that it has bucked when we observe a decrease in the applied force (assuming a displacement controlled loading). On the other hand we know...

What is the connection between the stability of solution of differential equation and structural stability from mathematical point of view?

For a fixed fixed - free Euler _bernoulli column, the buckling equation (which means it has already become unstable) is: y''+k2 y=k2*delta ... 1 Now (1) is stable (at least bounded though...

Is it necessary that the argument of natural logarithm is a a pure number>0 and should not have any dimension?

In 2D elasticity having axisymmetry condition we employ Airy's stress function (phi) in polar coordinate system.Here phi becomes a function only of radial distance (r). Integrating the subsequent...

Is there anybody working on beam bending?

In the area of large deflection with large strain problems, pertaining to beam or plate like structures along with plasticity. It will be good if somebody suggests me some reading materials.
