Mechanical Properties

Definition

Mechanical properties refer to the characteristics of materials that describe their behavior under applied forces or loads. These properties include strength, elasticity, plasticity, toughness, and hardness, which are essential for understanding how materials can be used in various applications. In the context of biomimetic materials, mechanical properties are critical for designing materials that mimic natural structures, optimize performance through hierarchical designs, and ensure durability when fabricated using modern techniques.
