A virtual framework for prediction of full-field elastic response of unidirectional composites

► Developed a method for predicting all possible elastic constants of UD composites. ► Used statistically realistic 3D RVE with pseudo-random fibre arrangement. ► Extended a 2D RVE macro-micro homogenization formulation to cope with 3D RVEs. ► Validation studies showed our method to give closest comparisons with experiments. ► Parametric studies show exciting features of the virtual framework and composites.
