Abstract Scope Aerospace engineering advances have led to continuous improvements in the design of next generation hypersonic vehicles. In combined extreme environments (CEE), fuselage panels of hypersonic vehicles will experience aggressive thermomechanical and acoustic loading. Panel design considerations in terms of dimensions, accent-cruise-decent missions, thermal cycling are some of the factors responsible for the anticipated thermomechanical fatigue experienced by these hypersonic vehicles. As a result, service conditions, failure predictions and lifespan of components has become critical points of discussions. In this study, a simulation approach is employed via a general-purpose finite element analysis (FEA) software ANSYS to develop force-displacement predictions of panel buckling. Although the candidate material for the study is 304 SS, the findings from this study can be implemented more generally. As a consequence, the design of future hypersonic vehicles having higher cyclic load profiles at extreme temperatures can be realized.
