One commonly used approach is the streamline methodology where fiber paths are obtained from the streamlines of the optimized fiber angle field ,,.

We, thus, printed the plate with a hole structure in three different lateral sizes each with a different degree of scale separation by holding the fiber diameter and thickness constant see Fig.
For the design automation step of our workflow, in this work and as in our previous studies , we adapted topology optimization with the Mori—Tanaka homogenization scheme ,, to simulate the homogenized material response of FRCs. The modularity of our workflow allows flexibility to replace each component with different processes as desired.
Compos Eng 2 3 :149—160• The angles are only shown for a quarter of the model and are symmetric about the prescribed symmetry planes. However, few studies are concerned with the experimental validation on the numerically predicted cure-induced temperature gradient or degree of cure as a whole.
Introduction This document is intended to outline the mechanics of fiber-reinforced laminated plates, leading to a computational scheme that relates the in-plane strain and curvature of a laminate to the tractions and bending moments imposed on it. A sample set of Matlab codes for determining the Pareto frontier in the problem of simultaneous optimization of E x and E y is available to download from .
We also connect our design approach to an additive manufacturing method through the stripe patterns algorithm.
Others ,  used numerical homogenization for microstructural design, either fiber-based  or arbitrary bi-material composites .
The comparison between numerical simulation results and experiment measurement data were performed to explore the practical temperature gradient and thermal boundary conditions during curing.
