Metal Forming Modelling Materials Properties Critical to Simulation of Hot Stamping
Reliable simulation of hot stamping process requires accurate material data. This paper describes the development of computer models that can provide many of the material data required, including TTT/CCT phase transformation diagrams, temperature dependent physical and thermophysical properties, as well as temperature and strain rate dependent mechanical properties including high temperature st...
متن کاملEvaluation of Ductile Damage Criteria in Hot Forming Processes
The process of ductile fracture which occurs due to the accumulation, growth and combination of defects or cracks of material is called ductile damage. Failure in materials can be predicted, using damage mechanics and damage criteria. On the other hand, most of the materials depended to the manufacturing process, are formed in warm or hot conditions so that; the temperature also affects on the ...
متن کاملCoupled numerical simulation of hot stamping process and experimental verification
Hot stamping process is a high non-linear process showing the effect on thermal, mechanical and metallurgical phenomena as they relate to each other. In order to carry out this coupled numerical simulation, fundamental thermal properties such as interfacial heat transfer coefficient and convection heat transfer coefficient as well as crucial mechanics properties were first investigated. Hot sta...
متن کاملForming of Multi layer Sheet Metal by Drawing Process: an Analysis and FEM Simulation
In this paper, the drawing process of multi-layer sheet metal through wedge shaped die has been analyzed using stream function and upper bound method. Typically a sandwich sheet contains three layers of metal, where the outer layers are of the same thickness and material and different from those of the inner layer. In this study, a new deformation model has been introduced in which inlet and ou...
متن کاملFEM Simulation of the stretch-forming of aircraft skins
The principle of this process is shown in Figure 1. Only one die (the stretch-block) is needed, which contains the shape of the part. The sheet, clamped with two gripper jaws, is formed around the stretch-block, when the grippers move along the given trajectories. Accurately shaped products can be obtained with minimal springback, when stretch deformation is added to the bending deformation of ...
