This paper gives a review for a new technique to give shape to metal by laser source is presented. Typically metal forming by Laser is contactless method in which laser beam is used as energy source and by inducing temperature induced stress in material, we can form material in various shapes. The main benefit of laser forming lies in its capability to form low ductility metal and with high acc...

 One of the surface defects that arise in sheet metal working is when the part removes from the die. Since there are no external forces to make this defect, the origin of such fail is known as residual stress. Residual stress can develop in sheet metal forming due to non uniform deformation. In this paper, the workpiece is carbon steel with different volume fractions and arrangement of ferrite ...

An alternative remeshing methodology for 3D Abaqus explicit analyses which utilizes mesh mapping is presented. Excessive element distortion in 3D large deformation analyses necessitates remeshing, however in Abaqus explicit, the standard 3D remeshing techniques limits the analyst’s choice of element type. The presented technique allows remeshing of 3D perfectly plastic fully integrated higher o...

In this paper, we propose a reliability–mechanical study combination for treating the metal forming process. This combination is based on the augmented Lagrangian method for solving the deterministic case and the response surface method. Our goal is the computation of the failure probability of the frictionless contact problem. Normally, contact problems in mechanics are particularly complex an...

The most often used friction model for sheet metal forming simulations is the relative simple Coulomb friction model. This paper presents a more advanced friction model for large scale forming simulations based on the surface change on the micro-scale. The surface texture of a material changes when two surfaces are in contact under a normal load. This is caused by flattening due to combined nor...

Expert system can be defined as an intelligent computer program, a repository of knowledge, a set of rules, like a human consultant, all aiming at delivering accurate solutions/suggestions to a problem at any level, say during plan, design, manufacture, and quality control. Some of the important definitions are quoted here. “An expert system is a computer system used to distribute the expertise...

This study details a new method to create materials by integrating polycyclic aromatic hydrocarbons into reactive transition-metal surfaces. We describe the interaction of hexabenzocoronene (1, HBC, Figure 1a) with a clean ruthenium surface. Interest in 1 and its interaction with transition-metal surfaces is driven by its relationship to the end cap of a carbon nanotube, to polynuclear aromatic...
