Plastic strain localization in polycrystalline titanium. numerical simulation

The deformation behavior of a polycrystalline titanium alloy is numerically simulated in terms of micromechanics and crystal plasticity theory. Based on experimental data, a three-dimensional polycrystalline structure is generated by the method of step-by-step packing. A crystal plasticity-based constitutive model of the grain behavior is constructed to take into account the crystal lattice geometry and dislocation glide in hexagonal metals. The boundary-value problem of the elastic-plastic deformation of model polycrystals is numerically solved by the finite-element method. In order to validate the numerical model, calculations are performed of the elastic-plastic deformation of titanium single crystals with different orientations of crystalline axes. Using the numerical approach, the texture effects on the plastic strain localization in polycrystalline titanium are numerically investigated.
