One critical problem of sheet formed products is its dimensional accuracy. This is related to springback (elastic recovery), after forming load releasing. It may happen in any forming process; however, it is easier noted ...

A phenomenological rate and state-variable friction law for the continuous sliding under lubricated and dry conditions, asit occurs in metal forming processes, is presented in this paper. The contact model is developed ...

The production of metallic junctions employing elastomers is an unconventional technique that has been in development in the last 20 years. The forming process gets successfull just if a simultaneous compression between ...

In order to achieve automation of the plate forming process by line heating, it is necessary to know in advance the deformation to be obtained under specific heating conditions. Currently, different methods exist to predict ...

Among the forming processes can be emphasized the metallic junction forming using elastomers. This forming process presents a considerable number of variables, as for instance: the definition of the necessary relationship ...

The oil exploitation and production at the pre-salt fields in a safety and efficient way depends on the development of materials that withstand the severe work conditions found in these fields. For instance, pipes, such ...
