Approximate postbuckling analysis of shear deformable laminates
PAMM, 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
Computer-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.

Surface Softness Tuning with Arch‐Forming Active Hydrogel Elements
Advanced 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 ...
