Notched specimen under compression for ductile failure criteria
Popis výsledku v původním jazyce
Notched specimen was designed for testing in compression. It was manufactured from the aluminium alloy 2024-T351, which is widely used in the aerospace, aeronautical and automotive industry. The test, among others, was used for the calibration of three uncoupled ductile fracture criteria dependent on the first invariant of stress tensor and third invariant of deviatoric stress tensor. The yielding was described by three plasticity models dependent on the second invariant of deviatoric stress tensor – proposed by von Mises, dependent on the second and third invariants of deviatoric stress tensor, and the most complex yield criterion dependent on the first invariant of stress tensor and second and third invariants of deviatoric stress tensor. All models were implemented into Abaqus commercial finite element code using VUMAT user subroutine. The ductile fracture prediction was carried out by widely used element deletion technique for specimen under compression. In the aftermath, the results were compared to experiments to see the performance of complex plasticity models with uncoupled fracture criteria.
