Correlation Studies of Different Decoupled Two-Scale Simulations for Lattice Structures

Sharing for the benefit of those who are interested: A new technical paper co-authored by researchers at the JAXA: Japan Aerospace Exploration Agency, The University of Tokyo and CYBERNET SYSTEMS CO.,LTD., was published in the Aerospace - a free-access journal by MDPI. The authors reckon that the study will provide a guideline for effective designs of high-performance lattice structures with architected materials.

Researchers used Multiscale.Sim, a multi-scale analysis and simulation tool embedded in Ansys® Workbench™, for the homogenization of lattice-based plates during this study.

Figure 1. A concept of computational homogenization for the lattice structure. Effective characteristics of a lattice structure constructed with periodic unit cells are evaluated based on computational homogenizations with the representative unit cell. The obtained effective properties are used to predict macroscopic responses of the structure with a homogenized structural model. (Image: Aerospace by MDPI)
