Numerical study of stress distribution and size effect during AZ31 nanoindentation
Original language description
A numerical study of the nano-indentation of the AZ31 alloy was performed in order to analyze the stress fields at the onset of twinning. The model considers indentation of the (10 (1) over bar0) and (1 (2) over bar 10) planes by a spherical indenter with radii of 5, 10 and 50 mu m. Material behavior is described by a crystal plasticity constitutive model with three critical resolved shear stresses for different slip modes. The CRSS values were obtained by fitting to experimental load-displacement curves. The stress and strain distributions are analyzed with a view to understanding twin initiation. The twins initiate during indentation at the stress level order of magnitude higher compare to uniaxial tests.
