【 摘 要 】

This paper studies the Algorithm of Free Frequency and Corresponding Forms of Free Oscillations Finding on the basis of the Finite Element Method in the form of Classical Mixed Method (FEM CMM). This form of FEM is alternative, with respect to the traditional travel and can be used to verify the results obtained from other numerical methods.
