Popis
Shrnutí:This study present a method to calculate first and second order displacement sensitivity based on Epsilon algorithm and improved Neumann series. In this paper, analytical expressions of first and second-order sensitivity are derived. They are then decomposed into vectors using the improved Newman series method. Finally, Epsilon is used to calculate the result. The method which is suitable for complex structure has the character of fast calculation and high efficiency. The high precision and fast convergence of the proposed method are proved by two numerical examples. The study show that the proposed method has engineering application value.
