The internal hydroforming of large stainless-steel eggshells from a stepped preform is investigated in this paper. nominal major and minor axes the eggshell were 1537 1070 mm, respectively. was fabricated thin-walled (1.9 mm thick) sheets comprised twelve conical segments inscribed inside target eggshell. then hydroformed, its wall thickness shape measured. yield load distribution material hard...
abstracthydroforming process is a deep stretching process only with the difference that a fluid is used instead of the mandrel. this paper investigates the hydroforming process of non-cylindrical and non-spherical geometries using finite element analysis software to calculate the influences of effective process parameters such as the coefficient of friction between the surfaces and the pressure...
Hydroforging is a hybrid forming operation whereby a thick tube is formed to a desired geometry by combining forging and hydroforming principles. Through this process hollow structures with high strength-to-weight ratio can be produced for applications in power transmission systems and other structural components that demands high strength-to-weight ratio. In this process, a thick tube is defor...

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...
One of the bellows producing method is hydroforming process .Whereas some factor of hydroforming process specially internal pressure affects on final characteristics produced bellows such as bursting, wrinkling and wall thickness distribution. In this paper the effect of internal pressure factor in final quality of produced bellows will be investigated. In simulation of process, ABAQUS/Explicit...
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 ...
