| Research Abstract |
The models to predict the load conditions have been built using near infrared spectra obtained from various load directions. Multivariate analysis indicated that the stress value at respective load conditions was clearly predicted with high accuracy. The major wood components, i. e. cellulose, hemicellulose and lignin showed characteristic behaviors according to the load conditions. Principal component analysis has revealed that the spectra collected from the stress conditions in elastic and plastic deformation were clearly separated into two groups.
