Abstract

This paper analyses the fatigue life prediction problem for fixed plate of helicopter in the case of cyclic loading using damage mechanics methods. The material parameters are obtained by the results of the fatigue test of standard specimens. According to the theory of damage mechanics, the closed solution of fixed plate's fatigue life is obtained. And the numerical solution is gotten through using finite element software ANSYS. Numerical solution, closed solutions and experimental results are consistent. This research provides a feasible way to predict the fatigue lives of structure members by means of damage mechanics.
