👉 The term "triaxial" refers to a type of material that is made up of three different layers, each with its own unique properties and behavior. Triaxial materials are typically composed of three distinct phases—crystalline, ductile, or ductile-ductile. This allows them to have a wide range of physical and mechanical properties, which can be used in a variety of applications. Triaxial materials can exhibit different behaviors depending on the composition and structure of their layers
