Extract

This note is devoted to the analysis of the initial buckling of an elastic sheet reinforced by a uniform non-buckling grid of stringers and skew ribs. The stringers and ribs enter the analysis through their influence on the stresses in the unbuckled sheet. Combinations of the following loadings in the plane of the reinforced sheet are considered: —

  1. (i) uniform direct loading normal to the ribs,

  2. (ii) uniform shear loading relative to axes perpendicular and parallel to the ribs.
