... recognized as a promising manufacturing process over conventional forming for the materials having decent formability. However, it does not give reliable results while forming hard to form materials. A few investigations revealed that heat plays a vital role in enhancing the formability. On heating...

... using different approaches and, therefore, most studies cannot be easily compared. Besides, some studies that measured the formability in SPIF using the classical limiting forming ratio (LFR) showed conflicting results that still need to be clarified. Under these circumstances, the aim of this work...

... (geometric inaccuracy) to improve multistage SPISF. Nirala and Agrawal [ 11 ] introduced a novel incremental toolpath based on fractal geometry theory for better stress distribution and formability. Duflou et al. [ 12 ] studied the effect of four process parameters: vertical step size, tool diameter, wall...

... hydroforming experiments suggested that, in general, formability of AA5754 can be significantly improved with slow forming rates (<0.02/s), high forming temperature (>200 °C), and biaxial loading (hydroforming) that can delay strain localization (necking). However, the effect of forming rate did...

Smith Previous studies have shown that the presence of a pulsed electrical current, applied during the deformation process of an aluminum specimen, can significantly improve the formability of the aluminum...

...Ho Choi; Muammer Koç; Jun Ni Hydroforming of lightweight materials at elevated temperature is a relatively new process with promises of increased formability at low internal pressure levels. In this study, the mechanism of warm hydroforming processes is presented in terms of its formability...

...Guosong Lin; Jing Li; S. Jack Hu; Wayne Cai Hemming is a manufacturing process of folding a panel onto itself or another sheet. Quality of hemming is characterized by geometry and formability. This paper presents a response surface study of three-dimensional (3D) curved-surface-curved-edge hemming...
