Bending refers to application of force to sheet metal, making it to curve at a specific angle and create the desired enclosure shape. Bending operation leads to deformation along a single axis. The operation of bending leads to both compression and tension within the sheet metal. Also, the external section of the material will experience tension and extend to a sizeable length.
Besides, the act of bending results in both tension and compression in the sheet metal, whilst the internal section endures compression and shrinks. The neutral axis denotes the boundary line within the sheet metal, through which no compression or tension forces are existing.
