ESDU 77014:2012

ESDU 77014 gives data for the analysis of a panel (that is, a
thin plate reinforced by orthogonal edge stiffeners) carrying a
shear load in which the plate has buckled to give a diagonal
tension field. The proportion of shear reacted by the tension can
be found using ESDU 77018. Data, based largely on a correlation of
experimental information, enable the following to be determined:
maximum shear stress at plate failure at a buckle or at the rivet
line, compressive stress in the stiffener, end load and bending
moment acting on the flanges as a result of the diagonal tension
field, the loading along the flange-to-plate connection, and the
secant and tangent moduli of the panel. A practical worked example
illustrates the use of the data.
