Defect modes

Defect modes are specific ways that imperfections or irregularities in a material, like cracks or holes, affect how it vibrates or responds to energy. Normally, materials have certain predictable vibration patterns, called modes. When a defect is present, it can create new, localized vibration patterns or change existing ones, potentially impacting the material's strength, durability, or performance. Understanding these defect modes helps engineers identify and analyze flaws, ensuring better material design, improved reliability, and early detection of problems before they cause failure.
