| Abstract: | Analysis of structural dynamic performance and response is the foundation to estimate fatigue life.Therefore,this paper summarizes two main engineering analysis methods for calculating the response of thin-wall structures subjected to acoustic loads in normal temperature and higher thermal environment.The methods includes: model analysis method;finite element method.In addition,the applied range and shortage of these methods are also presented.At last we give an outlook for the research works in aviation thin-wall structures fatigue life. |
