Abstract Incremental sheet forming (ISF) is an emerging technology for manufacturing metal components with fewer tools and equipment compared to conventional forming. In this process, generally performed without dies punches a simple hemispherical shaped tool can be used shaping the final component. Forming limit in incremental defined by maximum formable wall angle. Finite element analysis fra...

A new phenomenological constitutive model is proposed to predict the mechanical behaviour of thermoplastics in current research. The and method determine parameters are introduced. In model, a transition function enable smooth flow stress behaviours under both small-strain large-strain conditions. validating with testing data Polyetheretherketone (PEEK) Polycarbonate (PC), it found that this ab...

Electromagnetic forming is a high energy rate forming process. In this process, an electromagnetic Lorentz body force is used for deformation of products. In this article, Electromagnetic forming process was simulated for assembly of parts as an innovative method. In this research work, the effect of important parameters of process such as discharge energy, radius and width of rectangular groov...

Abstract—The numerical simulation based on the Finite Element Method (FEM) is widely used in academic institutes and in the industry. It is a useful tool to predict many phenomena present in the classical manufacturing forming processes such as fracture. But, the results of such numerical model depend strongly on the parameters of the constitutive behavior model. The influences of thermal and m...

Abstract Magnesium alloys, because of their good specific material strength, can be considered attractive by different industry fields, as the aerospace and automotive one. However, use is limited poor formability at room temperature. In this research, a numerical approach proposed in order to determine an analytical expression hot incremental forming processes. The model was developed using co...

An experimental test was carried out to explosively clad solution annealed Inconel 718 superalloy on quench-tempered AISI H13 hot tool steel. A wavy with vortices interface geometry was obtained from this experiment. A gradual change in the wavelength along the direction of welding was observed which was due to a change in the impact angle, following the plate contacts. In this paper, the exper...
