An Investigation on Three-Point Bending of Foam-Filled Double Tubes and Parameter Optimization Using Response Surface Methodology [PDF]
Mechanics of Advanced Composite Structures, 2021 The bending behavior of foam-filled double (FFD) tubes was studied in this study. The goal was to create an optimal structure that could absorb the most energy while weighing the least.

Experimental Investigation of the Effects of Irradiating Schemes in Laser Tube Bending Process
Metals, 2021 The laser tube bending process (LTBP) process is a thermal non-contact process for bending tubes with less springback and less thinning of the tube. In this paper, the laser tube bending process will be studied experimentally.

Endotracheal Tubes Design: The Role of Tube Bending [PDF]
Symmetry, 2021 Endotracheal tubes (ETT) passed inside the human trachea witness tube bending at different angles, affecting the local fluid flow dynamics. This induces a variable mechanical ventilation performance across patients’ comfortability levels. Our understanding of the local fluid flow dynamics phenomena is thus crucial to enhance the maneuverability of ETT ...

Springback Prediction of Free Bending Based on Experimental Method
Applied Sciences, 2023 The springback phenomenon has an impact on tube-processing quality during the free-bending process. For different pipe benders, the forming process is affected by different factors, such as gaps between the tube and the bending die and friction between ...

Springback optimization for CNC tube bending machine based on an artificial neural networks (ANNs) [PDF]
FME Transactions, 2023 Predicting the springback angle has become the major production problem among tube benders. Springback is where the tube on a mandrel-less rotary draw bending tends to bounce back after being bent when the clamps are released.
