Buckling Knockdown Factors for Hemispherical Foam Core Sandwich Shells With Single Dimple
In this study, nonlinear postbuckling analyses are performed using ABAQUS to derive the buckling knockdown factors (KDFs) for hemispherical foam core sandwich shells under external pressure.

Approximate postbuckling analysis of shear deformable laminates
Abstract In the lightweight design of aircraft, spacecraft and marine vessels, often advanced materials are utilised. Advanced materials such as laminated composites made of fibre‐reinforced plastics show transverse shear deformations if they are considered “thick” or possess little transverse shear stiffness.

Buckling Induced Strongly Nonlinear Vibration of Supercritical Axially Moving Beam
In this paper, the postbuckling problem and the free linear and nonlinear vibration surrounding postbuckling configuration are accurately analyzed. The placement of translating beams that undergo significant overall buckling deformations in this high ...

On polymorphic uncertainty modeling in shell buckling
Abstract Buckling is typically the governing failure mode of thin‐walled shells. In particular, geometric and material imperfections have a major influence on the buckling behavior. Small variations of imperfections have large effects on the load‐bearing behavior.

Postbuckling and Free Vibration of Multilayer Imperfect Nanobeams under a Pre-Stress Load
This paper investigates the postbuckling and free vibration response of geometrically imperfect multilayer nanobeams. The beam is assumed to be subjected to a pre-stress compressive load due to the manufacturing and its ends are kept at a fixed distance ...

Surface Softness Tuning with Arch‐Forming Active Hydrogel Elements
Thin active elements on rigid surfaces can be actuated for reversibly tuning mechanical contact properties from soft to hard. The concept and stimulus expansion model simulations of arch forming at the example of hydrogel beams are presented. Arch‐forming elements can be used to change the tactile properties interfaces or to provide adjustable ...
