| Abstract: |
| In this paper,the elastic bifurcation thermal buckling of a heated complex structure un-der the mechanical loading is carried out by means of finite element method.A correspondingcomputer program for the thermal buckling of complex structures with mechanical loadingand thermal loading is coded in FORTRAN 7 7 and is implemented on microcomputers andSUN 4/490 work station.The numerical results of some examples show that the bucklingcarrying capacity is large-scale decreased due to the thermal loading,The feasibility of study-ing the collaping macro-mechanism of complex structures such as the aircraft under mechani-cal loading and strong thermal loading is illustrated by the research achievement in this pa-per. |
