Scanning technique to identify biologically degraded wood

From: Experimental Techniques | Date: May 1, 1998| Author: | Copyright information

The USDA Forest Service, Forest Products Laboratory (FPL), has been developing nondestructive evaluation (NDE) techniques to identify degradation of wood in structures and the performance characteristics that remain in the structure. The FPL's work has focused on using stress wave transmission NDE techniques for both laboratory and field investigations.

In a previous publication,1 we reported on an inexpensive experimental technique that was developed to observe longitudinal stress wave behave for in small-sized wood specimens. The technique utilized a mechanical impactor to induce a wave in ...
