What is the spring back effect?

Question

Accepted Answer

Spring back effect is the tendency of a material to return to its original shape after being deformed.

Spring back effect occurs when a material is bent or stretched and then released, causing it to return to its original shape.
It is commonly observed in materials like metals and polymers.
The amount of spring back depends on the material's elasticity and the magnitude of the deformation.
Spring back can be a desirable or undesirable effect depending on the application. For example, in sheet metal forming, spring back can lead to dimensional inaccuracies.
To compensate for spring back, engineers may use techniques like over-bending or pre-stressing the material.

Accepted Answer

At the end of the forming process, when the part has been released from the forces of the forming tool, there is a distortion in the shape and dimension of the formed part. This distortion is termed springback.
