Have you ever done an analysis on a lattice structure? Lattice structures tend to be difficult to mesh and computationally expensive. Homogenization is an effective way to reduce the analysis cost of lattice structures. This article introduces homogenization to elastic matrices by numerical experiments and visualization of the homogenized elastic matrices.

In order to simulate a metamaterial structure efficiently, it is replaced by a uniform shell element.

The adidas "4DFWD" shoe, with a special 3D printed structure embedded in the midsole, has the function of converting the force of a step into propulsive force. This series of articles interprets this function as a mechanical metamaterial that converts compression into shear and explains how to design it. In this article, we will design a mechanical metamaterial with macro physical properties that convert compression to shear, measure its macro physical properties using the homogenization method, and conduct experiments by actually compressing a 3D printed specimen.
