Abstract
Accurately predicting the fatigue crack propagation (FCP) life of thin balcony opening corner structures with warping deformation using the FCP theory is a major challenging task. Herein, a procedure for analyzing the effect of warping deformation on the FCP in thin balcony opening corner structures is presented. According to the proposed method based on the modesuperposition to simulate the warping deformation (MSSWD), the stress intensity factors (SIFs) of cracks at the midpoint of balcony opening corners with warping deformation are appropriately modified. The FCP tests with reduced-scale models are also performed to provide experimental verification data for the given procedure. The fatigue lives of the specimens under various loads are calculated based on the modified SIFs and unique curve model and then are compared with the test data. The obtained results reveal that this approach can precisely predict the FCP lives of thin balcony opening corners with warping deformation.
