Abstract: The problem of buckling of curved shear panels of corrugated sheets, which is encountered in the design of long shells is examined theoretically. Overall panel buckling, and not local buckling, is analyzed. Thus, the corrugated sheets are treated as orthotropic curved plates. Equilibrium conditions, as well as geometric and elastic relations of a deformed infinitesimal element, are governed by two linear simultaneous coupled differential equations in deflection w and stress function F. Series presentation for w and F yielded a set of homogeneous linear algebraic equations in the unknown deflection coefficients. A nontrivial solution of these equations is possible provided that the determinant of their matrix is equal to zero. The eigenvalues of the shear load are calculated and only the lower value is considered. The few experiments available show reasonable agreement with the theoretically obtained ones. For practical use, curves are given for the calculation of critical shear load.
