Buckling Thresholds for Pre-Loaded Spherical Shells Subject to Localized Blasts

This paper investigates the robustness against localized impacts of elastic spherical shells pre-loaded under uniform external pressure. We subjected a pre-loaded spherical shell that is clamped at

Nonlinear dynamics of spherical shells buckling under step pressure

Damping plays an important role in dynamic buckling because of the time-dependent nonlinear interaction among modes, particularly the interaction between the spherically symmetric ‘breathing' mode and the buckling mode.

Nondestructive Prediction of the Buckling Load of Imperfect Shells.

This study introduces a nonlinear description where finite-amplitude perturbations trigger buckling and provides a new promising framework to understand shell buckling, and more generally, imperfection-sensitive instabilities.

Buckling Analyses of Spherical Shells by the Finite Element Method Based on the Willis-Form Equations

Buckling analysis of spherical shells under external pressure is a crucial problem in mechanical and aerospace engineering and the buckling loads obtained by classical methods are shown to be underestimated.

Buckling of pressurized spherical shells containing a through-thickness defect

Delayed buckling of spherical shells due to viscoelastic knockdown of the critical load

We performed dynamic pressure buckling experiments on defect-seeded spherical shells made of a common silicone elastomer. Unlike in quasi-static experiments, shells buckled at ostensibly subcritical

Buckling of a pressurized hemispherical shell subjected to a probing force

We study the buckling of hemispherical elastic shells subjected to the combined effect of pressure loading and a probing force. We perform an experimental investigation using thin shells of nearly

Nonlinear Buckling Interaction for Spherical Shells Subject to Pressure and Probing Forces

Elastic spherical shells loaded under uniform pressure are subject to equal and opposite compressive probing forces at their poles to trigger and explore buckling. When the shells support external

The Geometric Role of Precisely Engineered Imperfections on the Critical Buckling Load of Spherical Elastic Shells

We study the effect of a dimplelike geometric imperfection on the critical buckling load of spherical elastic shells under pressure loading. This investigation combines precision experiments, finite

Buckling of a pressurized hemispherical shell subjected to a probing force

We study the buckling of hemispherical elastic shells subjected to the combined effect of pressure loading and a probing force. We perform an experimental investigation using thin shells of nearly

Shock-Sensitivity in Shell-Like Structures: With Simulations of Spherical Shell Buckling

Assessment in general terms how a single control can capture remote saddle solutions is assessed: in particular, how a symmetric probe could locate an asymmetric solution.

Buckling of a spherical shell under external pressure and inward concentrated load: Asymptotic solution

An asymptotic solution is suggested for a thin isotropic spherical shell subject to uniform external pressure and concentrated load. The pressure is the main load and a concentrated lateral load is

A Theory for the Buckling of Thin Shells

In a series of papers written by the present author in collaboration with Th. von Karman and Louis G. Dunn, the effect of curvature of a structure on its buckling characteristics was investigated.

Determination of realistic worst imperfection for cylindrical shells using surrogate model

Thin-walled cylindrical shells subjected to axial compression are sensitive to initial geometrical imperfections. Firstly, the influence of a single dimple imperfection on the load-carrying capacity

These fully nonlinear solutions embedded in the stability boundary of the unbuckled state constitute critical shape deformations and may be a step towards explaining when the buckling and subsequent collapse of an axially loaded cylinder shell is triggered.
