- Abstract:
- There is a demand of a system for the nondestructive control of one of the basic quality parameters for wood-based low-density boards (Softboard). A relatively non-destructive method was analyzed on a purpose to find a parameter to measure that has the biggest possible correlation with the bending strength. 13 different softboards were investigated using two different techniques. The boards were tested using another two non-destructive methods: velocity measurement of ultrasonic Lamb waves and impact parameters measurement. Out of all experiment results the highest correlation between bending strength and the conical indenter impact pulse peak force was found.
