| Abstract: | Based on an analysis of free vibrations of flexural beam with continuous variation in cross-section, the characteristic equations of free vibrations of flexural bars with step tapered cross-section are established. Thus, the general equations of frequency and function of the model shape are derived. The equations can be solved numerically by computer. Comparison of numerical solution with the exact solution is also given in the paper. |
