For several years, the aviation industry has seen dynamic growth in use of composite materials due to their low weight and high stiffness. Composites are being considered as a means building lighter, safer, more fuel-efficient automobiles. Composite material relatively new kind unmanned aerial vehicle, commonly known drone. Incremental forming methods allow be quickly formed without need manufa...

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...

Much of the attention on simulation software in recent years has been focused on the modelling of bulk metal forming processes such as forging, rolling and extrusion. However, there are numerous applications for the simulation of sheet forming processes and indeed many pressings suppliers in the automotive industry are more advanced in the use of simulation than their forging counterparts. The ...

Two-layer metallic sheets have wide applications in various industries due to their superlative characteristics. This paper presents analytical model to investigate the formability of two-layer sheets based on Marciniak and Kuckzinsky (M-K) method using Barlat and Lian non-quadratic yield criterion. FEM simulation is also performed to calculate the forming limits based on bifurcation theory. Fo...

High speed and absence of a precise control over pressure distribution confine sheet Electromagnetic Forming into a die to simple shapes having shallow depth. It is possible to reach a higher depth by using a convex punch instead of a concave die. In this study, sheet Electromagnetic Forming on a punch and sheet Electromagnetic Forming into a die are investigated. The electromagnetic part of th...
