Abstract   Fiber-metal laminates (FMLs) are new type of composite materials which could improve defects of traditional composites in ductility, formability, impact and damage tolerance. Drawing behavior of a thermoplastic based FML was investigated consisting of glass-fiber reinforced polypropylene composite laminate and aluminum AA1200-O as the core and skin layers, respectively. The effects o...

Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...

this paper investigates the forming of sheet metal forming under cycling loading by considering the bauschinger effect. different proposed plasticity models which can handle this kind of deformation process have been reviewed in details. for instance, isotropic, kinematic and combined forms in the linear and non-linear cases including the well-known yoshida and chaboche's models have been ...

In order to solve the problem that due to the unreasonable parameter Settings when use CAE analysis to produce the cars covering parts mould, such as sheet wrinkling, cracking, and more than an acceptable range of rebound. This article used CAE analysis software to find relatively reasonable parameters to achieve a reasonable analysis in the process of sheet metal forming defects and to put for...

In the article the changes associated with construction of machines used in die and die-less sheet metal forming have been presented. The selected future directions of development in new technologies and machines for sheet metal forming taking into account modern blank holding systems in the process of deep drawing have been indicated. Also the tendencies in introduction of new technologies and...

Deep drawing process is one of the widely used methods in sheet-metal forming. With the deep drawing method, products of various geometrical shapes such as saucepans, tubes, perfume and soft drink cans can be obtained easily. Therefore, the optimization of the deep drawing process is very important for the industry. In conventional deep drawing method, no angle is given to the surfaces of die a...
