摘要：

Fatigue failure, which occurs in many engineering components and structures in service, is actually attributed to the multiaxial loads. This study is aimed to estimate/prescience life of main landing gear of a medium multi-utility aircraft under multiaxial loadings. In this analysis we studied the various loading conditions among them few are the spin-up, spring-back and lateral drift loading. The equivalent stress based multiaxial fatigue criteria (Sines and Crosslands) is employed for the determination of equivalent stress due to multiaxial loading and Palmgren Miner's theory used for calculating total damage and consequently the fatigue life. It is seen that the multiaxial fatigue numerical analysis render lower life than the maximum uni-axial life value. (C) 2014 The Authors. Published by Elsevier Ltd.
