Adaptable Tile‐Based Pneumatic Origami through Structurally Coupled Localized Actuation

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents tile‐based pneumatic origami structures with rigid tiles and flexible fabric creases, achieving adaptable properties including morphing shape, selective multistability, and tunable stiffness. Independently pressurized folding bladders at each crease enable structurally coupled localized actuation of origami structures.

Maximum Angle of Stability of a Wet Granular Pile

open access: yes, 2005
Anyone who has built a sandcastle recognizes that the addition of liquid to granular materials increases their stability. However, measurements of this increased stability often conflict with theory and with each other [1-7].

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Optimizing Post Friction Stir Welding Heat Treatment in Dissimilar Friction Stir Welded 6061/AlSi10MgMn Joints for Electrical Vehicle Battery Housing

open access: yesAdvanced Engineering Materials, EarlyView.
Microstructural evolution and hardness optimization along the cross‐section of friction stir welded AA6061/AlSi10MgMn joints, for electric vehicle battery housings, were investigated. Postweld aging between 170°C and 220°C enhances hardness uniformity within the nugget zone.
