Deformation in a material caused by stress results in a quantity known as strain. It is calculated as the change in length divided by the original length. For example, if a 10-centimeter bar stretches by 1 centimeter under tensile force, the strain is 0.1, representing a 10% elongation.
Understanding deformation is fundamental to engineering design. Accurately predicting and quantifying it ensures structural integrity, preventing failures and optimizing material usage. This knowledge has evolved alongside materials science, contributing to advancements in construction, manufacturing, and various other industries reliant on robust and durable components.
