Volume 6, Issue 2 , June 2017, , Pages 115-127


  In the present study, mechanical properties and low cycle fatigue behavior of a solid-solutionized AA6061 aluminum alloy produced by equal channel angular pressing (ECAP) process were investigated. The grain refinement after two passes of ECAP significantly increased the yield stress and ultimate tensile ...  Read More

Volume 5, Issue 2 , June 2016, , Pages 97-109


  Laser forming is a thermal forming process which uses laser beam irradiation to produce the desired final forms. In this article, the effect of temperature gradient across  Al 6061-T6 aluminum sheets on bending angle is studied. Input parameters including laser power, scan velocity, beam diameter, ...  Read More

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 , June 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
