“…Interestingly, this result coincides with the upper bound implied by the positivity of [15] and also ensures continuity of the hoop stress at r ¼ L FFT . Thus, energy minimization naturally yields a value for the stress at the tip of the wrinkles that smoothly matches the flat region in the film to the wrinkled one.…”

“…However, buckling becomes likely whenever compressive stresses develop in some region of the plate, and this does not require the presence of any compressive external loads. Indeed, this was the situation in some recent works [3,4] where the concerted effect of inhomogeneous pre-buckling deformations and tensile loads led to localized wrinkling patterns (when global tensile loads are involved, it is customary to use the words 'buckling' and 'wrinkling' somewhat interchangeably). Although the resulting linear equations were not solvable in closed form, the presence of initial tension introduced a large nondimensional parameter that played a key role in obtaining analytic formulae for characterizing both the critical load and the buckling pattern.…”
