抄録

In our previous studies, first, for linear elastic deformation, an intelligent hybrid method that automatically detects and eliminates the errors and noises in a full-field experimental measurement field was developed. Next, for nonlinear elastic-plastic deformation, the authors derived an incremental variational principle minimizing the experimental measurement errors. Concepts of incremental self-restoration forces and energies were also presented. Furthermore, the authors developed an intelligent hybrid method based on this incremental variational principle. In this study, the progressing nonlinear elastic-plastic deformation field near a crack tip in A533B CT specimen is evaluated by using the intelligent hybrid method. The intelligent hybrid method demonstrates automatic detection and elimination of the measurement errors and smooth visualization of stress and strain distributions. Furthermore, the intelligent hybrid method automatically achieves the path independence of the T integral, restoring the path-dependence caused by the measurement errors. This paper provides the foundation of an intelligent measurement and visualization of displacement and stress fields in actual structural components.
