1. Analysis of deep drawing process to predict the forming severity considering inverse finite element and extended strain-based forming limit diagram

Mehdi Bostan Shirin; Ramin Hashemi; Ahmad Assempour

Volume 8, Issue 1 , Summer and Autumn 2018, , Pages 39-48


  An enhanced unfolding Inverse Finite Element Method (IFEM) has been used together with an extended strain-based forming limit diagram (EFLD) to develop a fast and reliable approach to predict the feasibility of the deep drawing process of a part and determining where the failure or defects can occur. ...  Read More

2. An Experimental Study on the process parameters of Incremental Forming of Explosively-Welded Al/Cu Bimetal

Mohammad Honarpisheh; Ahmad Gheysarian

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


  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

3. Prediction of earing in deep drawing of anisotropic aluminum alloy sheet using BBC2003 yield criterion

S. Izadpanah; S. H. Ghaderi; M. Gerdooei

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


  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

6. Initial blank design of deep drawn orthotropic materials using inverse finite element method

Hashem Zamanian; Mehdi Bostan Shirin; Ahmad Assempour

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


  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

7. Finite element comparison of single, bi-layered and three-layered tube hydroforming processes

Gh. Payganeh; J. Shahbazi Karami; K. Malekzadeh Fard

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


  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
