In the present study, the deformation behavior upon reverse loading in a commercially pure titanium sheet was studied by means of experiments and crystal plasticity finite-element simulations. When the sheet was subjected to reverse loading from tension to compression, strong Bauschinger effect occurred after the stress reversal, followed by a linear strain-hardening behavior. In the case of r everse loading from compression to tension, strong Bauschinger effect also occurred after the stress reversal as in the former case. Thereafter, in contrast, a small but clear sigmoidal curve was presented. The simulation results were in good agreement with the experimental results. The simulation results showed that this strain-hardening behavior upon co mpression-tension would be b ecause of the activity of { 1012 } detwinning in the beginning of tension.
