Derivative procedure for bem based computation of change in natural frequency with crack size
Source abstract
Abstract
An efficient boundary element method (BEM) based computation of change in natural frequencies with crack size is proposed. The accuracy of the method demonstrated through three case studies is found to be good. The results are not so dependent on the type of element used around the crack tip.
