Numerical Approach of Viscous Flow Containing Short Fiber by SPH Method
The simulation methodology for the injection molding is proposed using SPH method in this paper. First, the specific algorism based on the SPH method is designed to simulate the solidification of the molding resin. The algorism is employed to simulate a plate of typical resin by two dimensional SPH method, focusing on the distribution of resin velocity and temperature in thickness direction. And then the viscous flows containing short fibers are simulated using the algorism. The results showed that the SPH method using the algorism can clearly simulate the formation of the solid layer along the mold surface and has a prediction potential of the resin solidification behavior.
