Correlating Ultrasonic Velocity in DC04 with Microstructure for Quantification of Ductile Damage

Journal of Manufacturing and Materials Processing, 2023
The detection of ductile damage by image-based methods is time-consuming and typically probes only small areas. It is therefore of great interest for various cold forming processes, such as sheet-bulk metal forming, to develop new methods that can be ...

Development of a High-Performance Building Material Using Wood-based Corrugated Panels Manufactured via Cold-Forming Technique

BioResources, 2023
A wood-based sandwich panel with a corrugated core was developed as a building material. A matched-die mold manufactured from commercial plywood was used to fabricate the corrugated panels through a cold-forming process.

Wood-based Corrugated Core Sandwich Panels Manufactured Using a Wooden Mold

BioResources, 2023
A wooden matched-die mold was manufactured to develop wood-based corrugated panels. Wood veneers brushed with resin were cold pressed between the mold halves and formed into a corrugated geometry.

Numerical investigation of manufacturing hollow preforms by combining the processes backward cup extrusion and piercing

MATEC Web of Conferences, 2016
Hollow or tubular preforms are used to meet lightweight requirements and reduce production costs of cold formed components. In order to increase efficiency of manufacturing, a combined forming process was developed, which will be presented in this paper:
