✦ Synopsis

This note concerns the Mode I stress intensity factors at edge cracks in strips under pure bending. When these cracks penetrate three quarters or more of the width of the strip, expressions in standard handbooks can give rise to distinctly different results for K~. By applying an appropriately tested finite element procedure, guidance is provided in the selection of the correct value of K~ for such configurations.
