Abstract Scope |
Titanium alloys potentially exhibit micro textured regions (MTRs), also called macro-zones, which have a detrimental influence on the performance under cyclic loadings, but recent studies revealed a significant influence on the monotonic tensile behavior as well. Numerical simulations of the macroscopic response of large 3D aggregates containing MTRs of different shapes and sizes were performed using a crystal plasticity model based on fast Fourier transforms. The macroscopic response as well as the stress and strain fields at the microscopic scale were found to be affected by the presence of MTR. The importance of an explicit modeling of these MTRs is highlighted, in particular for cyclic loading conditions. |
