摘要：

The use of the finite element method for dynamic analysis of multicorp systems with elastic elements implies the solving of numerous problems related to the computational techniques and the particularity of such a study in comparison with the techniques applied to the classic finite elements For such systems, special features arise from the non-linearity of the matrix coefficients appearing in the differential equation system that describe the mechanical system response and the occurrence of additional terms within these equations. In the paper a comparison is made between the finite element results of the modal response considering the third degree polynomial shape functions and the fifth degree polynomial shape functions. It is also analyzed how the number of finite elements considered for the analysis of a beam can influence the obtained results.
