This software enables the design and simulation of compliant rolling-contact architected materials (CRAMs). It also generates an image of how each layer within a designed CRAM should be fabricated with straight flexure straps. Click here to download the necessary files (i.e., CRAMtool.m, CRAMtool.fig, and images.mat) and put the files in the same folder on your computer. Then open and run the file CRAMtool.m to launch the tool.

This software enables the design and simulation of directionally compliant metamaterials (DCMs). It also generates animations of their designed degrees of freedom. Click here to download the necessary files (i.e., MaterialDesignGUI.m, MaterialDesignGUI.fig, and images.mat) and put the files in the same folder on your computer. Then open and run the file MaterialDesignGUI.m to launch the tool.

This software enables the design and simulation of sequential metamaterials with alternating Poisson's ratios. It generates animations of the unit cells deforming next to a corresponding plot showing the resulting Poisson's ratio. Click here to download the necessary files and put the files in the same folder on your computer. Then open and run the file Metamaterial.m to launch the tool.
