Abstract

Results are reported for an assessment of methods for predicting strength of wood, wood-based, or related material. Research directly applicable to nondestructive strength prediction was very limited. In wood, strength prediction research is limited to vibration decay, wave attenuation, and multiparameter "degradation models." Nonwood methods with potential application to wood include spectral response and techniques based on the ratio of energy dissipated per bending cycle and bending elastic energy at maximum amplitude. Conclusions drawn summarize the current status of nondestructive strength prediction research in various materials. Several research options are discussed for nondestructively predicting strength loss in treated piling.
