The change in the shape and size of a part under external forces is called deformation.
It refers to the changes in shape and size of metal materials under the action of external forces.
It refers to the changes in shape and size of metal materials under the action of external forces.
The plastic deformation of metal without heating is called cold plastic deformation. For example, processing methods such as stamping, cold bending, cold drawing, and cold heading all fall under cold plastic deformation.
It is a physical phenomenon in which deformation occurs under the action of external forces under certain conditions. Plastic deformation: irreversible; Elastic deformation: reversible
The deformation of metal materials can be divided into plastic deformation and elastic deformation. Plastic deformation occurs when a metal material is deformed under external forces, and this deformation does not revert once the external forces are removed； Elastic deformation, on the other hand, can be restored.
