TL;DR: In this paper, the authors used finite element (FE) analysis to model and explain the evolution and distribution of contact pressure over the die radius, throughout the duration of a channel forming process.

TL;DR: In this article, a method to numerically quantify the contact sliding distance experienced during a typical sheet metal stamping process is proposed, which can be applied as a general approach to study any other two-body sliding contact situations.

TL;DR: In this article, the authors studied the correlation between emitted sound signals and the wear state of sheet metal stamping tools and found that the corrupting sources generated by the tooling of the stamping press and surrounding machinery have higher amplitudes compared to that of the sound emitted by the operation itself.

TL;DR: In this paper, a method to statistically study the forming and springback problems of TRANSformation Induced Plasticity (TRIP) through an industrial case study was developed, where the sensitivity of predictions to four user input parameters in implicit and explicit sheet metal forming codes was investigated.

TL;DR: In this paper, the authors provide a qualitative description of the evolution and distribution of contact pressure at the die radius for a typical channel forming process, and identify that three distinct phases exist.
