Question

The phenomenon of springback happens in a bending operation due to the following reason

• A. Due to the presence of elastic energy in the bent part
• B. Due to the presence of plastic energy in the bent part
• C. Due to insufficient force imparted on the bent part
• D. Due to excessive force imparted on the bent part

Answer 1

Answer:

A. Due to the presence of elastic energy in the bent part

Springback is the tendency of a material to return to its original shape after being bent. It occurs because the bending process stores elastic energy in the material. When the bending force is released, this elastic energy is released, causing the material to partially return to its original shape.
