Flexible Pipe Manufacturing Processes are increasingly being subjected to the need to improve the resilience of materials, due to the higher depth of oil exploration. Among these materials is the steel strip responsible for manufacturing the first layer of the flexible pipe, called by the carcass, which is liable for withstanding the internal pressure of the product passing through the inner of the pipe. Currently, steel strips with bigger size are being used in the Duplex material. The mechanical and microstructural characteristics were evaluated. This work aims at modelling of a mechanical forming process of Duplex and SuperDuplex stainless steel strips through Computational Simulation Software (ANSYS LS-Dyna and ABAQUS) in order to perform explicit dynamic analyzes in which the material, in which the material supports higher efforts in a short period of time. The Explicit Computational Simulation was made associated with an industrial case, obtaining a simulation compatible with the real process, being possible to validate the model. Finally, after the validation of the model, a computational analysis was done between the Duplex and Super Duplex materials, in which it was possible to detect some places of the strip with greater stresses.
