The study aims to fully explicate the bending behavior of tea stalks under condition large deflection, which is crucial improve working performance mechanized harvesting equipment. mechanical model stalk was assumed be a non-prismatic beam with virtual internodes that could differ from actual internodes. With model, can freely divided into multiple internodes, whose flexural rigidities determin...

The paper shows the effects of behaviour of loading during the buckling process on the value of critical force and initial stability of post-buckling path for elastic, non-prismatic columns. Perturbation method combined with Croll’s manoeuvre makes it possible to derive general formulae for the first or the second correction of the force, and hence to analyze stability in the post-buckling rang...

The present paper combines an effective beam theorywith a simple and accurate numerical technique opening the door to the prediction of the structural behavior of planar beams characterized by a continuous variation of the cross-section geometry, that in general deeply influences the stress distribution and, therefore, leads to non-trivial constitutive relations. Accounting for these peculiar a...
