1. Acoustic System for Investigation of Physical Characteristics of Metals Performed by : Saleh Samara Fouad Haddad Fouad Haddad Supervised by : Dr. Michael Gandelsman

2. Abstract : There are many different ways used in order to analyze physical attributes of metals. Not always these ways give an accurate definition of the metal's real state, and the rate of exhaustiveness of the metal, which is very important in many systems in order to insure a proper operation. The offered way that we implement in our project is based on analyzing the acoustic waves and the vibrations developed as a result of a hit of a hardened ball on the examined metal.
