Stents for angioplasty have been extensively used to treat coronary diseases. The aim of this study is to analyze the expansion of the stent and the contact with the artery using tube hydroforming simulation. In the simulation, the contact stress and the final shape of the artery after stent expansion process using the Stampack (®;) software will be studied. A model of a commercial stent made o...

In real crash cases, simple bending behavior is not common. this case, using the three-point test to examine provides a closer simulation in terms of representation structure under loading. It seen literature that products with tube sections are generally used as door im-pact beams. On other hand, when examining developed high strength steels, it studies on profiles only evaluated hydroforming....

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...
