Abstract

In this paper a buckling design rule for stringer stiffened curved CFRP panels subjected to combined mechanical and thermal loading is derived by parametric studies with the finite element system ANSYS. At first a finite element model to simulate the buckling behaviour of such panels is established and validated with test results from a former study. Then loading and boundary conditions are adapted to those of the Thermex B testing site at DLR in Braunschweig, and results of linear bifurcation analyses with constant material properties under combined mechanical and thermal load are presented. Additional nonlinear computations with temperature dependent material properties confirm the results of the linear computations. The results of all computations are summarized as the design rule looked for, and then verified by tests.
