Abstract: In this paper,the two dimensional standing waves on circular plate whose support coincided with vibration source are measured,calculated and simulated by experiment and MATLAB. The testing results follow with MATLAB’s simulation very well. It has shown a method to measure the Young modulus. It is a significant practice for college physics experiment and simulation.
