Strain is a measure of deformation representing the displacement between particles in a material body that results from an applied stress. It quantifies how much a material stretches or compresses under external forces, and this concept is crucial for understanding how materials respond to various types of loading. In structural characterization methods, assessing strain helps in determining the mechanical properties and stability of materials, providing insight into their structural integrity.
