Young's modulus (or Young modulus) is a mechanical property of solid materials that measures the tensile or compressive stiffness when the force is applied lengthwise. It is the modulus of elasticity for tension or axial compression.

Young's modulus (E) describes tensile and compressive elasticity, or the tendency of an object to deform along an axis when opposing forces are applied along that axis; it is defined as the ratio of tensile stress to tensile strain. It is often referred to simply as the elastic modulus.
Young's modulus (E or Y) is a measure of a solid's stiffness or resistance to elastic deformation under load. It relates stress ( force per unit area) to strain (proportional deformation) along an axis or line.

Sometimes referred to as the modulus of elasticity, Young’s modulus is equal to the longitudinal stress divided by the strain.
Define a relação entre tensão (força por unidade de área) e deformação (deformação proporcional) em um material no regime de elasticidade linear de uma deformação uniaxial. O módulo de Young tem o nome do cientista britânico do século XIX Thomas Young.
