Size matters! At least when it comes down to the finite element size. To cover different layers of fiber orientation in a fiber reinforced material it is necessary to use a fine mesh, but to keep the cpu time low, it has to be as coarse as possible. I´d like to share with you the following experience: - Midplane meshes of course are the best opportunity to caver as much information over the thickness as possible since it is simply your choice how many layers you´d like to use. - A Hexahedral mesh is nice to keep dof low, but can only cover as many information as there are elements over the thickness. - Tetrahedral meshes usually take less time in preprosessing and are usually the best choice to represent complex geometries. For short fiber reinforced materials they have another benefit. The center of each Tet-element is slighty shifted over the thickness and therefore, covers different information. In this picture you see the fiber orientation distribution function over the thickness (legend) and an example micrograph showing this effect in a real part. The different mesh types have different pros and cons when used to take these effects into account:
Saving Material Without Performance Loss Challenge Reducing the weight without loss of usability and strength Optimizing the manufacturing process Solution Injection molding simulation to optimize the part production and to create the fiber orientation for the new designed part Taking into account these results to perform most realistic mechanical simulation Results Significant material and cost savings due to optimized geometry Faster and more economic production process
