TL;DR: In this article, the authors provide an overview of the state of the art in such joining processes, including cold welding, friction stir welding, self-pierce riveting, mechanical clinching and joining by forming.

TL;DR: In this paper, the authors give an overview of these efforts substituting environmentally hazardous lubricants in cold, warm and hot forging as well as sheet forming and punching/blanking by new, less harmful lubricants and furthermore describe other measures directed towards the same goal such as development of anti-seizure tool materials and coatings and application of structured workpiece and tool surfaces.

TL;DR: In this article, a closed-form theoretical analysis of the fundamentals of single point incremental forming is presented, which is based on membrane analysis with bi-directional in-plane contact friction and is focused on the extreme modes of deformation that are likely to be found in singlepoint incremental forming processes.

TL;DR: In this article, the authors constructed a closed-form analytical model that is capable of dealing with the fundamentals of single-point incremental forming and explaining the experimements of SPIF.

TL;DR: In this paper, a new theoretical model for rotational symmetric single point incremental forming (SPIF) was developed under membrane analysis with bi-directional in-plane contact friction forces.
