Outline of Final Research Achievements

The sonic tomography, two dimensional images of velocity distribution, was applied on wood disks with artificially chiseled cavities. As cavity area increased, the sound velocity shifted to a lower side and the estimated decay-area increased. Irregular shapes of cavities caused overestimation of cavity area.
Reduction of wood weight, sound velocity and wood strength was measured after inoculating wood decay fungi on test pieces of heartwood. During the progress of wood decay, reduction of sound velocity correlated linearly with weight loss. However, especially in early stage, wood strength was greatly reduced than weight and sound velocity.
Consideration of these results improve the accuracy of nondestructive decay testing using sonic tomography.
