In-line Springback Measurement for Tube Bending Using a Laser System

Effect of Cooling on Bending Angle and Microstructure in Laser Tube Bending with Circumferential Scanning

Laser tube bending is a flexible forming process. Two irradiation methods of axial and circumferential scanning are generally used to form metal tubes. The two most important disadvantages of circumferential scanning are its lower bending angle and the time interval required between each scan for cooling purpose. In this research, a novel cooling strategy during laser tube bending with circumfe...

Springback Modeling in L-bending Process Using Continuum Damage Mechanics Concept

Springback is one of the most common and important issues in metal forming area. Due to the fact that springback depends on a variety of parameters, it is hard to predict. Hence, in this paper, the effect of continuum damage mechanics (CDM) on springback was investigated based on the Lemaitre isotropic unified damage law. Swift’s hardening law was employed to describe isotropic hardening behavi...

Numerical and experimental investigation of laser induced tube bending

Mechanisms of the process are examined to better understand the deformation characteristics such as slightly protruded shape at the intrados, wall thickness variation, cross-section ovalization, bending radius, and asymmetry. A finite element model is developed and validated by experimental observations. Factors important to characteristics of deformation are experimentally and numerically inve...
