A study was performed to analyze different methods of manufacturing a full scale car frame for the Smart Cities Citycar, a folding electric vehicle being designed at the MIT Media Lab, as well as a half-scale prototype for testing driving and folding systems. Through looking at two case studies for similarly sized automobiles as well as analyzing the compatibility of metal casting, stamping, co...

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....
