Abstract
AbstractThe objective of this work is to present a simplified, nonetheless representative first stage of a phenomenological model to predict the crack evolution of ductile fracture in single crystals. The proposed numerical approach is carried out by merging a conventional well‐ stablished elasto‐plastic crystal plasticity model and a well‐known phase‐field model (PFM) modified to predict ductile fracture. A two‐dymensional initial boundary‐value problem of ductile fracture is introduced considering a single crystal Nickel‐base superalloy material. the model is implemented into the finite element context subjected to a one‐dimensional tension test (displacement‐controlled).
