An ultrasonic system to measure the strength of wood

This project report purposes the design and development of low cost 40kHz ultrasonic system for measuring the strength of the wood. Ultrasonic measurement techniques now a days are advancing exponentially because there is no need to alter the physical or chemical properties of the subject sample. Th...
