Each Aero-Vehicle body structures has a tendency to exhume weariness, when a part is more than once stacked the subsequent impact is known as exhaustion. In this paper we compute life of a segment subjected to total weakness stacking. As a rule, the weight punishment can't go on without serious consequences by utilizing weariness limit as suitable anxiety. Most auxiliary segments and parts are affected by unpredictable fluctuating hassles in which the greatest and least burdens are ceaselessly changing. Therefore, need is to utilize a weakness hypothesis which will dissect the harm as a consequence of shifting sizes of anxiety cycles. The paper portrays examination of exhaustion life of a segment under combined weakness stacking utilizing palmgren digger's principle. Keywords: High cycle stress, low cycle stress, residual crack growth, cumulative fatigue damage, damage tolerance.
