An approximate method of calculating the fundamental frequency of bending vibrations of multi-cracked beams is proposed on the basis of a modification of the method for single-cracked structures.

As the complexity of ship structural designs keeps on increasing, the use of statistical techniques to build approximation models for expensive computer analysis is getting popular.

Based on this,we calculate interaction van der Waals coefficient using [1,0]、[2,1]pade approximation and get a good result.
