Approximate postbuckling analysis of shear deformable laminates

open access: yesPAMM, Volume 23, Issue 4, December 2023., 2023
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.

On polymorphic uncertainty modeling in shell buckling

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 38, Issue 18, Page 2632-2647, December 2023., 2023
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

open access: yesApplied Sciences, 2018
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

open access: yesAdvanced Engineering Materials, Volume 25, Issue 16, August 2023., 2023
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 ...
