Thermal post-buckling behavior of patched laminated panels under uniform and non-uniform temperature distributions

摘要

The thermal post-buckling analysis of patched laminated panels under uniform and non-uniform temperature distributions has bee performed using a finite element method based on the Hellinger-Reissner principle with independent strain, which is fee of shear locking. The cylindrical arc-length method is adopted to obtain a non-linear solution. The accuracy of the present analysis is demonstrated for benchmark problems. The effects of lamination angle, direction and location of patches are investigated on thermal post-buckling behavior under uniform and non-uniform temperature distributions.
