Auxetic materials have a negative Poisson's ratio, therefore they expand in all directions when stretched. High-resolution 3D scan data of auxetic foam was obtained from the synchrotron facilities at the University of Washington. The data was automatically segmented and meshed using Simpleware ScanIP and the Simpleware FE module. The simulations were performed using ABAQUS®, Fluent and LS-DYNA®.
A high resolution MicroCT scan (3µm) of the auxetic foam was imported into Simpleware ScanIP. Noise reduction on the background image was applied and main regions were segmented using the automated threshold tool. Two masks representing the foam and surrounding air were extracted.
Simpleware FE was used to generate a multipart mesh for finite element analysis within minutes. The software guaranties matching nodes and elements at the contact surface. Also node sets were created at the boundaries of the material. Several meshes were exported to ABAQUS, Fluent and LS-DYNA®.
