Annealing is a crucial part of the plastics molding process. The annealing process will heat the material and maintain it at a specific temperature for a while, and then slowly cool down. The main purpose of annealing is to relieve residual stress. Annealing is also applied to increase the material ductility and toughness of the products and generate a special microstructure.
Moldex3D Stress enables users to observe the product deformation behavior under the hot oven annealing process. The annealing simulation would then provide the displacement results, Von Mises Stress, Shear Stress, and the Temperature distribution results based on the Warp calculation results. (Fig. 1)
In the Moldex3D R17 version, the annealing simulation also considers the fibre effect on the geometry deformation so that a more accurate warp result can be attained.
Annealing Simulation Considers Fibre Orientation Effect Procedure
Step 1: Mack sure the Run fibre orientation analysis options are enabled in the Flow/Pack tab (Enhanced Solver or Standard Solver) and the Warp tab of Computation Parameter.
Step 2: The default Micro-mechanics model is the Mori-Tanaka model, and users can choose other models if needed. The Micro-mechanics model of the Annealing simulation follows the Warp tab setting and the model type can be checked the function in the Log file.
Step 3: In the Stress tab, select the Analysis type as Annealing. Then, run the Stress-S analysis after the standard analysis sequence (CFPCW) simulation is finished.
Note: Users can recheck the Log (*.lgs) file. It records the setting which is synchronized with the Warp simulation. (*.lgw)
