| Abstract Scope |
A crystal plasticity finite element method (CPFEM) model has been developed to predict the mechanical behavior of 0.1 mm thick Grade 1 commercially pure titanium (CP-Ti) sheets. In CP-Ti materials, typical tension-compression anisotropy and unique stress-strain responses are observed during various deformation modes, which are common in hexagonal close-packed metals. The model aims to capture the aforementioned characteristics by focusing on twinning and detwinning phenomena. Specifically, twinning induced plasticity and slips in twinned crystals are incorporated into the FE model through a volume-averaged homogenization scheme, where the volume fraction of each twinned region can be updated based on the twinning/detwinning activity. Experimental data confirms the model’s accuracy in predicting anisotropic mechanical behaviors and texture evolution. This highlights its potential to investigate and predict the plasticity of Ti sheet metals under complex loading scenarios. |
