A structural analysis method for plastics (SAMP) based on injection molding and microstructures

摘要

An advanced Structural Analysis Method for fiber filled Plastics (SAMP) based on injection molding and their microstructures was proposed. This proposed SAMP combines injection molding and microstructures together to analyze the mechanical behavior considering the fiber orientation and anisotropic materials. The fiber orientations are obtained through injection molding simulation, and the nonlinear anisotropic materials are obtained through mean-field homogenization at the microstructures. This SAMP are classed into 3 modules: material analysis, injection analysis and structure analysis. Both of the material analysis and injection analysis are coupled together into subsequent structure analysis to obtain reasonable and more accurate simulation results.
