For ̄ exible manufacture of a doubly curved sheet metal, a new sheet metal forming process is proposed that uses a movable punch set composed of two pairs of lower support punches and one upper centre punch. The process is characterized by ̄ exibility compared with the existing conventional processes because it does not require any complex-shaped die and the loss of material is minimized by unc...

Deep drawing of two-layer sheet is a suitable way to achieve product with a desired shape and desired properties in sheet metal forming technology. Control of deep drawing parameter such as thinning is the most important challenge in this process. The most difficult part of this challenge is differences in material properties and geometry of each layer. In this paper, numerical approach has bee...

Fibre metal laminates, hybrid composite materials built up from interlaced layers of thin metals and fibre reinforced adhesives, are future-proof used in the production passenger aircraft, yachts, sailplanes, racing cars, sports equipment. The most commercially available fibre–metal laminates carbon aluminium aramid glass laminates. This review emphasises developing technologies for forming met...

The cup drawing is a basic deep drawing process. Thus, understanding the mechanics ofthe cup drawing process helps in determining the general parameters that affect the deep drawingprocess. There are mainly two methods of analysis; experimental and analytical/numerical.Experimental analysis can be useful in analyzing the process to determine the process parameters thatproduce a defect free prod...

This paper provides an overview of the development a 3D formed and metal-based facade element that combines custom design solar thermal functionality. To achieve this, novel simplified collector structure was developed using sheet metal half-shells with integrated channel on inside special absorber coating outside. The were manufactured by highly innovative incremental forming (ISF), which allo...
