DEFORM 2D ROLLING MULTIPLE OPERATIONS

http://www.cadfamily.com/downinfo/301343.html

24.1. Create a regular rolling problem

Start a new DEFORM-2D problem with problem ID 2D_ROLLING. Enter the Pre-
processor and import ROLLING_LAB.KEY from directory \LABS. Generate Database
ROLLING_LAB.DB. Do not exit the Pre-processor.

24.2. Define multiple operations
In the Pre-processor, click menu bar ??Tools?? and select ??Rolling multiple operation??. The
following dialog should be displayed. Assign corresponding objects as shown. The
Primary die (always the upper roll) is determined already. The Primary workpiece is the deformable object that will contact the die (the strain rate of the primary workpiece is used sas a stopping criterion). The Pushed workpiece is the deformable object that contacts the Pusher. There is no lower roll in this case. The Primary workpiece and the Pushed workpiece might be different if there is more than one slab to be sandwiched. Click ??Next after all objects are set (See Figure 24.1).
