Forward modeling of diffraction peaks is a potential way to compare the results of theoretical mechanical simulations and experimental X-ray diffraction (XRD) data recorded during in situ experiments. As the input data are the strain or displacement field within a representative volume of the material containing dislocations, a computer-aided efficient and accurate method to generate these fields is necessary. With this aim, a current and promising numerical method is based on the use of the fast Fourier transform (FFT)-based method.

- Near β titanium alloys are becoming competitive options for airframe forging, with up to 40% β-phase volume affecting their mechanical properties.
- An advanced elasto-viscoplastic model examines how elastic anisotropy influences tensile behavior at varying strain rates; it shows differences in mechanical performance based on elastic constants.
- The findings indicate that elastic anisotropy alters slip activities, leading to a shift in dominant slip systems with {112} <111> becoming more prevalent during plastic deformation, compared to isotropic cases.
