A feasibility study of continuous grain refinement of sheet metal
Ha, Taekwang; Murudkar, Rahul; Hartwig, Karl; Welo, Torgeir; Ringen, Geir; Wang, Jyhwen (Peer reviewed; Journal article, 2020)Various severe plastic deformation (SPD) techniques have been used to develop ultrafine-grained (UFG) materials to enhance material properties. Equal channel angular extrusion/pressing (ECAE/ECAP) is an effective technique ... -
Improving Friction Drilling and Joining through Controlled Material Flow
Su, Kuan-Yu; Welo, Torgeir; Wang, Jyhwen (Journal article; Peer reviewed, 2018)Friction drilling is a novel hole-making process that can be performed on thin-walled sheet metals. The friction between a rapid-rotating conical tool and a sheet metal workpiece generates heat to soften and displace the ... -
In-line Springback Measurement for Tube Bending Using a Laser System
Ha, Taekwang; Ma, Jun; Blindheim, Jørgen; Welo, Torgeir; Ringen, Geir; Wang, Jyhwen (Peer reviewed; Journal article, 2020)Tube bending process is extensively used for many industrial fields such as the automotive, shipbuilding, and aircraft manufacturing industries. However, one limitation of the tube bending process is that it is not easy ... -
On measuring, prediction and control of 3D profile bending towards Industry 4.0
Ha, Taekwang (Doctoral theses at NTNU;2022:346, Doctoral thesis, 2022)Aluminum profile bending is one of the methods providing potential to reduce weight and improve fuel efficiency in automotive, aerospace, and other industries. Most of manufacturers make efforts to reduce the number of ... -
A strategy for on-machine springback measurement in rotary draw bending using digital image-based laser tracking
Ha, Taekwang; Welo, Torgeir; Ringen, Geir; Wang, Jyhwen (Peer reviewed; Journal article, 2021)Rotary draw bending is a commonly used metal forming technique for profile bending. Due to the elastic recovery of the material, springback compensation to control the bent product quality is one of the critical manufacturing ... -
Structure-Processing-Property Relationships of 3D Printed Porous Polymeric Materials
Cipriani, Ciera; Ha, Taekwang; Martinez Defilló, Oliver; Myneni, Manoj; Wang, Yifei; Benjamin, Chandler; Wang, Jyhwen; Pentzer, Emily; Wei, Peiran (Peer reviewed; Journal article, 2021)Imparting porosity to 3D printed polymeric materials is an attractive option for producing lightweight, flexible, customizable objects such as sensors and garments. Although methods currently exist to introduce pores into ...
