| Abstract Scope |
Shear cutting process simulation alone already represents a challenging task, but the numerical analysis of multi-stage shear cutting process is even more challenging. Despite the numerical challenges, also the experimental validation of simulation models represents a major challenge, especially regarding the development of the shear affected zone. Therefore, in this work we address the experimental analysis of multi-stage shear cutting as a basis for validation and, moreover, for data-based modelling approaches. We present an in situ test design and measurement setup that preserves the process boundary conditions of shear cutting. An enhanced high-speed optical full-field evaluation method enables local and time-resolved measurement of strain fields and strain rate fields for each shear cutting stage. A mapping of these state variables between the individual cuts enables us to analyze consistently the shear affected zone throughout the entire multi-stage process and thus to characterize the final state of the shear zone experimentally. |
