New Interpolation Method for Free Vibration and Stability Analyses of Cracked Beams

The introduction of the stiffness reduction function evolved from the need for modification of the classical finite element formulation for the analysis of cracked beam-like structures. The parameters of a cracked beam are defined by interpolation of the two original and destination state conditions in an interpolation method derived by the innovative use of the stiffness reduction function. As a result, the analysis reduces to a simple formation similar to the equivalent Euler buckling load by defining the equivalent length factor for free vibration and the effective length factor for buckling analysis. Concise formulation and comparison of the results with those of the others enables verification of the effectiveness of the work.
