Mathematical Model of the Strip Rolling Made of the Sinterized Metallic Powders
Petrea, Ionel; Istrate, Sorin Miltiade (Universitatea "Dunărea de Jos" din Galați, 2005)The minimum-power method has been used to investigate the final ratio soft-layer thickness to tough-layer thickness in bimetals with porous layer rolling. The velocity fields has been determined and the total deformation ... -
Modelling of the Flow and Deformation Fields at teh Profiles Rolling by Field Lines Method
Cănănău, Nicolae; Petrea, Ionel; Corobete, Gheorghe (Universitatea "Dunărea de Jos" din Galați, 2005)This paper presents a method for modeling of the rolling process based at the deformable continuous medium mechanics, the theory of field lines. The rolling of the profiles and plates may be evaluated as the plane strain ...
