Larger bending radii tend to produce less spring back compared to smaller radii. Factor 2#: Relative Bending Radius The bending radius of the tool used to bend the metal affects the amount of spring back. Materials with a higher elastic modulus and yield strength are more likely to experience greater spring back. The material properties of the metal, such as its elastic modulus, yield strength, and work hardening behavior, affect the amount of spring back. The higher the yield point of the material, the smaller the modulus of elasticity, and the more intense the work hardening, the greater the rebound.
