Forming of aluminum sheets in T-temper is a much sought after industrial process, especially in the aircraft industry. However, the success of this process largely hinges on the ability to predict springback accurately. Aluminum ...

Improving the accuracy of virtual prototypes helps to shorten product development times and reduces the number of physical prototypes required. One way in which the accuracy of crash analysis can be improved is to include the effects ...

Superplastic forming process has been a standard manufacturing process in aircraft industry and its applications in other industries are increasing. Superplasticity is utilised in forming parts which can not be produced technically or ...

Over the past two decades, the finite element analysis (FEA) has emerged as one of the most important engineering tools in the many industries, due to its flexibility and accuracy in prediction. Nowadays, it is widely used in sheet ...

Metal-Plastic-Metal (MPM) sheets consists of two metal sheets bonded together by a thin polymer layer. Modelling this sheet structure with a single shell element gives a too stiff response. The large shear deformation in the polymer ...

Active hydro mechanical forming (AHMF) has been developed in order to meet the demand of the automotive industry for economical production of sheet metal parts with more individuality in small lot sizes. Conventional deep drawing of ...

Wear prediction necessitates the investigation of elastic stresses developed in the workpiece material due to impact and sliding of abrasive particles in tribological contact situations. LS-Dyna implicit finite element analysis is used ...

The conventional progressive stamping process used in producing connector pin makes the pin-shift from side to side due to elastic recovery reffered to springback phenomenon. As the solution of this problem, the reverse stamping ...

Foam materials are widely used in automotive industry such as energy absorbers and comfort enhancers. Because of high energy absorbing capability of foams, they became very important in vehicle crashworthiness. So in this manner, FE ...

Quasi-static, quasi-dynamic and dynamic compression tests have been performed on a nitrogen alloyed austenitic stainless steel. This alloy achieves a high hardening modulus and a good ductility at all strain rates. In addition, this ...
