Several thick steel plates are bent by hand.
12mm thick steel plate can be bent. According to relevant data, bending is not about thickness, but the ductility in materials science is the theoretical attribute of bending. Steel plate is a metal material with good ductility and will not break when bending. It is difficult to bend only when it is thick, and it takes a lot of external force to complete the bending, not that it cannot be bent. This theoretical problem must be clarified.
