Modélisation et étude 3D des phénomènes de cisaillement adiabatiques dans les procédés de mise en forme à grande vitesse

Abstract : Despite promising results high-speed machining is still not widely used in manufacturing due to the lack of understanding in Adiabatic Shear Band (ASB) phenomenon.
This work presents the development of numerical tools to support both the adaptive simulation and the physical study of ASB in 3D high speed machining process. The use of an adaptive Arbitrary Lagrangian Eulerian (ALE) sequential model developed within Forge3 software allows automatically simulating successive ASB in 3D for the first time. The physical study of the numerical results allows proposing an innovative description of ASB formation. Due to the need for extensive computational resource, a new highly parallelized finite element code called Forge++ is developed. It includes new numerical algorithms such as fully implicit coupling, Residual Free Buble (RFB) stabilization and parallel recovery by patch methods that support better modeling ASB.
