Process simulation for improved competitiveness

In numerical terms, the simulation of manufacturing processes must take into account many non-linear physical phenomena:

• materials with elastoplastic or viscoplastic behavior ;

• high deformation and high deformation speed ;

• contact between material and tool.

In recent years, significant progress has been made in the development of manufacturing process simulation software and associated methodologies. As in the field of design, process engineers used to carry out physical tests on the feasibility of producing a deep-drawn or forged part by adjusting various machine parameters. In addition to formability, and by minimizing the number of passes, the aim is to ensure the health of the formed part, notably the absence of localized tearing or...
