The Theory of Elasticity

The Theory of Elasticity describes how materials deform under applied forces—stretching, compressing, or twisting—and then return to their original shape once the force is removed. It explains the relationship between the applied forces, the resulting deformations, and the internal stresses within the material. This theory helps engineers predict how structures like bridges, aircraft, and buildings respond to loads, ensuring safety and durability. Essentially, it models the elastic behavior of materials, emphasizing that within certain limits, deformation is reversible and proportional to the applied force.
