Abstract Scope |
A representative volume element (RVE) is the smallest possible volume element of a material which is statistically representative of the macroscopic properties. The extended time required to capture 3D microstructural data and to run full-field micromechanical simulations drive a need for determination and implementation of RVEs. Far-field high energy x-ray diffraction experiments were carried out to study RVE size vs micromechanical response. These results were supplemented by simulation work on the effect of varying texture on volume element size. Distance metrics (e.g. Hellinger distance) were applied to resolved shear stress distributions throughout the work to evaluate RVE size. The work intends to help improve efficiency in both 3D data acquisition as well as efficiency in performing micromechanical simulations. |
