Definition: Adherences refers to the relationship between a material surface or component, such as an element in a composite structure, and its surroundings. In other words, it is the mutual interaction of the surface or element with its environment that determines how the surface responds to external forces. Adherences can occur at any scale from small-scale elements (e.g., atoms, molecules) to large-scale structures like buildings, roads, and bridges. They are fundamental in various fields such as engineering, architecture, materials science, and physics. Adherences are important because they allow a material to exert force on its surroundings while also being subject to forces applied by the environment. Some of the types of adherences include: - Chemical bonds: Bonds between atoms or molecules - Electrostatics: Forces caused by the separation of charged particles like electrons in solids and liquids - Gravitational: Forces that are produced by gravity, such as the weight of an object - Elastic: Forces that occur when a material is stretched, compressed, or pulled Adherences can be classified into two categories based on their strength: - Strong adherences: Adherences with forces greater than tensile or compressive stresses. - Weak adherences: Adherences with less than the strength of tensile or compressive stresses. Adherences are crucial in designing and fabricating materials for various applications due to their flexibility and adaptability. They allow for precise control over the material's properties and behavior under different conditions.
