The strength of the molding of Cyclo Olefin polymer (COP) was estimated by the non-linear finite element method (non-linear FEM) and its accuracy was examined. The true stress-strain curve of COP, which is necessary to analyze the stress distribution of molding by non-linear FEM, was determined by the optimum method based on the try and error. The analysis by use of the estimated true stress-strain curve predicated exactly the nominal stress-strain curve obtained from the unaixal tensile experiment. The criterion of the brittle fracture of COP was determined from both the three point bending test and the non-linear FEM analysis. It was confirmed that the analysis of non-linear FEM predicated well the strength of the molding of COP.
