Volume 7, Issue 1 , Summer and Autumn 2017, , Pages 73-83

http://dx.doi.org/10.22061/jcarme.2017.646

Abstract
  Single point incremental sheet metal forming is a sheet metal forming process that forms products without the complex dies and tools with low cost. In this study, the incremental sheet metal forming process has been experimentally investigated on the explosively-welded Al/Cu bimetal sheets. Also, the ...  Read More

Volume 6, Issue 2 , Winter and Spring 2017, , Pages 47-55

http://dx.doi.org/10.22061/jcarme.2017.583

Abstract
  This paper investigates the earing phenomenon in deep drawing of AA3105 aluminum alloy, experimentally and numerically. Earing defect is mainly attributed to the plastic anisotropy of sheet metal. In order to control such defect, predicting the evolution of ears in sheet metal forming analyses becomes ...  Read More

Volume 3, Issue 2 , Winter and Spring 2014, , Pages 125-134

http://dx.doi.org/10.22061/jcarme.2014.66

Abstract
  In this work, an inverse finite element formulation was modified for considering material anisotropy in obtaining blank shape and forming severity of deep drawn orthotropic parts. In this procedure, geometry of final part and thickness of initial blank sheet were known. After applying ideal forming formulations ...  Read More

Volume 2, Issue 2 , Winter and Spring 2013, , Pages 69-80

http://dx.doi.org/10.22061/jcarme.2013.54

Abstract
  In this paper, single, bi-layered and three-layered tube hydroforming processes were numerically simulated using the finite element method. It was found that the final bulges heights resulted from the models were in good agreement with the experimental results. Three types of modeling were kept with ...  Read More
