The two developed codes enable easy intergranular fracture simulations in Abaqus, as well as the automatic creation of different grain structures to reproduce sample-to-sample variability observed in experiments. These scripts extend the simulation capabilities of the finite element solver Abaqus.
Two codes have been developed: one allows columnar polycrystal geometries generated by software such as Neper or DREAM3D to be imported into the Complete Abaqus Environment for further geometric manipulation and meshing with arbitrary element types; the other code generates zero thickness, four noded interface elements at the boundaries between the crystals. Together these allow intergranular fracture simulations to be performed easily in Abaqus. This approach can automatically create different grain structures and allows the mechanical properties of metals and other crystalline materials to be simulated. This is important as it enables the sample to sample variability of fracture and mechanical properties that is observed in experiments to be reproduced. These scripts extend the simulation capabilities of the finite element solver Abaqus. (C) 2020 The Author(s). Published by Elsevier B.V.
