development of new technologies and combined with creativity and innovation, plays the fundamental role in developing of any community′s value. thus, in this research the design and production of hydroforming device was introduced. one of the best and most efficient technologies in the world of metal forming is wind turbine blade producing with hydroforming method which seems as an innovative m...

A critical air velocity analysis was performed using a numerical model adapted for the eastern tunnel tube of Kastelec road in Slovenia. This allowed efficiency fans to be tested, which is required maintain appropriate traffic conditions and prescribed safety tunnel. At velocity, that is, at an lower than one, where spread smoke can still effectively controlled ensure time safe evacuation passe...

This paper presents evaluation and effect of blank radius on radial stresses through mathematical formulations in hydroforming deep drawing process using castor oil medium. Hydraulic pressure can enhance the capabilities of the basic deep drawing process for making cups. In hydroforming deep drawing process, applying the hydraulic pressure on blank periphery in radial direction. It is obtained ...
