| Outline of Final Research Achievements |
A CAE system was established to reproduce the deformation behavior of advanced materials, such as fiber-reinforced thermoplastics and ultrafine-grained metal materials. Such advanced materials will be rapidly used as structural materials in the future. We numerically predicted the yield function used in CAE for structural analysis based on the experimental multiscale mechanics. The deformation behavior of advanced materials was described based on information on the microstructure obtained from experimental observations. The estimation system for contours of constant plastic work was improved by comparing the analysis results with the experimental results of microstructural observations and biaxial tensile tests. By installing the yield function into general-purpose structural analysis software, it is possible to seamlessly connect a series of processes from material design to development and practical use using CAE.
