Crystals are known for their beauty and elegance, but their microstructure can be complex, making mathematical modeling challenging. Researchers from The University of Osaka used differential geometry to describe the mechanics of crystals and their defects in a recent article in Royal Society Open Science.

In an ideal crystal, atoms are arranged in a perfect pattern, but most crystals have small defects like missing atoms or extra bonds. Understanding these defects is crucial as they can impact the mechanical properties of materials.

Lead author Shunsuke Kobayashi explains that defects come in various forms, such as dislocations and disclinations, which have different effects on symmetry. Integrating these defects into a single mathematical theory has been a challenge.

By using differential geometry, the research team found a way to reconcile the differences between various defects. This approach allowed them to describe the topological properties of defects and derive analytical expressions for stress fields caused by these defects.

The team believes that their geometric approach will inspire the design of materials with specific properties by leveraging defects. This study showcases how mathematics can help us understand the beauty of nature.
