Large ellipsoid parts are prone to wrinkle when forming by using traditional stamping. Aiming solve the wrinkling problem in large parts, EMIF method with a variable blank holder is proposed this paper. The numerical simulation has shown that sheet material near is, as consequence of stamping, subjected circumferential compressive stress. When drawing height was 100 mm, metal notably wrinkled. ...

In order to take up some challenges in metal forming coming from the recent environmental stakes, Electromagnetic Forming and Electro-Hydraulic processes have been developed at industrial scale, using advantages of high strain rates. Such progress has possible particular thanks emergence strongly coupled simulation tools. this article, examples selected applications deep forming, postforming, e...

Noncontact modulation calorimetry using electromagnetic heating and radiative heat loss under ultrahighvacuum conditions has been applied to levitated solid, liquid, and metastable liquid samples. This experiment requires a reduced gravity environment over an extended period of time and allows the measurement of several thermophysical properties, such as the enthalpy of fusion and crystallizati...
