000015145 520__ $$2eng$$aA comprehensive experimental study on plastic deformation and damage in titanium was conducted. The ex-situ and in-situ X-ray tomography measurements conducted reveal that damage distribution and its evolution in titanium is markedly different than in a typical FCC material such as copper. Theoretically, it is shown that only by modeling both the anisotropy and the tension-compression asymmetry in plastic behavior it is possible to realistically predict Ti behavior. Specifically, for a smooth axisymmetric specimen subject to uniaxial tension, the model developed predicts that damage initiates at the center of the specimen, and is diffuse; the level of damage close to failure being very low. On the other hand, for a notched specimen subject to the same loading the model predicts that damage initiates at the outer surface of the specimen, and further grows from the outer surface to the center of the specimen, which corroborates with the in-situ tomography data.
