Flat plates subjected to tensile loads may buckle locally in the presence of
geometric discontinuities such as cracks, holes or varying dimensions

However, it appears to be surprising that even in the absence of any geometric
discontinuity, buckling due to global tension occurs as a result of special
This effect can be observed during the stretching of thin strips, where high
wave number buckling modes can affect large areas.
In order to study this phenomenon and to find explanations, computational
and analytical investigations were performed.
A novel diagram for buckling coefficients is presented, enabling the
determination of critical longitudinal stresses.
