The classical lateral buckling of a straight drill string confined within an inclined cylindrical borehole is formulated as a singularly perturbed boundary-value problem which is subsequently explored using asymptotic techniques. In particular, the l

The work described in this paper is concerned with providing a rational asymptotic analysis of the wrinkling bifurcation experienced by a thin elastic hemispherical segment subjected to vertical tensile forces on its upper rim. This is achieved by co

The work presented here revisits the classical bifurcation problem for an axially compressed thin elastic circular cylinder when the nonlinear pre-buckling bending deformations are taken into account. Suitable scaling arguments and singular perturbat

Weakly clamped uniformly stretched thin elastic plates can experience edge buckling when subjected to a transverse pressure. This situation is revisited here for a circular plate, under the assumption of finite rotations and negligible bending stiffn

This work re-visits the finite pure bending problem for circular cylindrical shells within the elastic range. The interest here is primarily directed towards the bifurcation instabilities of such configurations when the progressive flattening of the

Bifurcations of thin circular elastic plates subjected to uniform normal pressure are explored by taking into account the flexural compliance of the edge restraint. This effect is accounted for by formally reinforcing the outer rim of the plate with

This work presents a detailed asymptotic description of the neutral stability envelope for the linear bifurcations of a shallow conical shell subjected to lateral pressure. The eighth-order boundary-eigenvalue problem investigated originates in the D

In the previous chapter we saw how the solutions of two-dimensional approximations in isotropic Linear Elasticity can be obtained from the Airy stress potential \(\varPhi \) that satisfies a bi-harmonic equation (either homogeneous or inhomogeneous).
