There is always a certain amount of springback deformation in a metal forming process. The high strength steel is becoming a more attractive choice for many applications when low weight of the structure is of importance. One major ...

This paper presents the results of applying the finite element method to calculating the spring back of an automotive hood assembly, and its application to the functional build method. The assembly was comprised of six individual ...

Manufacturing process simulation using finite element techniques has immensely contributed to ensuring the success of concurrent design methodologies. However, Finite Element Methods (FEM) is computationally expensive and consequently ...

The authors would like to present the whole procedure of using dynamic explicit finite element method to aid multi-stage miniature stamping die design. How to cost down and time saving are the key issues for tool maker in Taiwan. It ...

This paper is concerned with closing a gap in the process chain of metal forming. Tools for simulating the metal forming process like LS-DYNA® produce output geometries and stress information which cannot be easily re-imported in ...

Since the beginning of the 90s Finite Element Analysis (FEA) Forming Simulation has gained importance in design and realization of hydroformed components [1]. It has been used in process design from the first layout to serial ...

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 ...
