Abstract Large deformations under in-plane compression of paperboard appear in forming processes like hydroforming, pressforming and deep drawing, but the mechanisms deformation have not been studied on a micromechanical level. A constrained test is presented. This allows for compression, buckling, wrinkling compaction. The realized using DEBEN CT-500 in-situ tester laboratory microtomography s...

This study presents a multi-walled poly(ethylene glycol) diacrylate hydrogel tube formed by the simple self-folding of a bi-layered hydrogel patch. The gel tube has the capability to release encapsulated molecules through designated pathways in a sustained manner. Therefore, the gel tube encapsulating the vascular endothelial growth factor significantly increases the vascular densities and vess...

The widely adopted the high strength steel tube is an important way to solve lightweight body and collision safety. traditional pressure hydroforming hot gas forming through “expansion” deformation form hollow parts, internal driving force. There are some industrial difficulties such as heavy dependence on pressure, wall thickness thinning low production efficiency, which limits application of ...
