In the forming process, both sheet metal and plastic are bent to a specific bend angle. When the material is then released from the pressure of forming stresses within the bend (tension outside, the compression inside) causes the bend angle to open and the radius to open. Lobster Development Software . FastSHAPES® is the generic name for a suite of Plate & Sheet development software programs specifically designed for heavy fabrication where the main jointing technology is welding. The LOBSTER software module is for the development of tapered segmental bends, commonly known as lobster back bends, in sheet and plate.
