Long free strips of small thickness frequently show a wavy surface being the
consequence of buckling due to residual stresses.
The paper deals with the derivation of the corresponding relations under
conditions which are frequently met in the case of edge wave buckling of
rolled strips or in deployable structures.
It is shown that an increasing global tension force does not only lead to
increased critical stress intensity but also produces shorter buckling waves
concentrated towards the edges of the strip.
By introducing dimensionless quantities, diagrams and formulas are provided
which allow the determination of critical loading combinations.
Asymptotic considerations are also presented.
