| Popis: | A study of combined thermal andmechanical buckling of stiffened cylindrical shells using the structural geometry of a preliminary supersonic transport fuselage design from 1970 is presented. The buckling analysis is performed using BOSOR4, a nonlinear axisymmetric shell-of-revolution analysis code. The mechanical load is from axial compression and internal pressure and the thermal loading is from heated skins. Results indicate that the location of longitudinal eccentric stiffening has a significant effect on the thermal and axial buckling strength of longitudinally stiffened shells with and without ring frames. Buckling-interaction curves of the results with the associated mode shapes and a surface plot of the results are presented in which the eccentricity of the stringer, axial load, and temperature load are varied. |
