NDT Natural Oscillation Technique for Wooden Pole Strength

NDT natural oscillation technique for biological damage level of wooden pole is presented. The biological damage level depends on wooden pole strength which can be evaluated via frequency band of natural frequency spectrum. Actual physical model in presented. Some investigations of wooden pole strength were undertaken for three lots of products. Experimental results agreed in principle with physical model.

Keywords: strength, natural oscillation, frequency range, displacement vector, wooden poles.
