Fundamentals of Elasticity,ormable bodies as structures. Hooke’s law was discovered in 1660. Robert Hooke (1635–1703) was an English physicist. His important law of elasticity, known as Hooke’s law (1660), states that the stretching of a solid is proportional to the force applied to it. He published his law in 1678 .
