In January 2024, a groundbreaking study titled “Unveiling the Secrets of Plasticity in 3D Cracks – Understanding the Behavior of Materials Under Extreme Conditions” was presented at the annual meeting of the American Society of Mechanical Engineers. This research focused on plasticity 3D cracks, revealing the intricate mechanics underlying crack propagation and material strength.
Conch Shells: A Source of Inspiration
By studying conch shells, engineers discovered that their unique architecture makes them ten times tougher than nacre, commonly known as mother of pearl. This superior toughness arises from a three-tiered structure that makes it difficult for cracks to spread and grow. The material’s zigzag matrix forces cracks to navigate a labyrinthine path, significantly increasing its resistance to fractures.
