Aircraft structure subjected to elevated temperature presents a challenging design environment as damaging thermal stress can result. Thermal stress in a structural component is typically alleviated by accommodating the thermal expansion. However, very little work has been done that directly addresses the situation where such a prescription for expansion is not possible. When a structural component is failing due to tensile stresses which are thermally induced, the answer to the question of how best to stiffen the structure in this environment is far from trivial. This work demonstrates that conventional stiffening techniques, for example, thickness increase, may actually increase the rate of damage, as well as generate additional load that must be reacted by sub- and surrounding structure. Because flat plates representa common structural element that is susceptible to developing tensile stresses due to thermally induced out-of-plane deformation, a simple strip model which represents cylindrical bending in a semi-infinite flat plate is chosen as the focus of this work.
