A method to analyze the components with crack is presented under the background of a real engineering, and an experiment is carried out on the site to check it.It shows that the result of the computation coincides with that of the experiment approximately, which means the method is dependable and practicable adequately. So it is helpful to solve the problems in engineering practice.
