AD 427: Typographical error in P419

A few eagle-eyed readers have noticed a typographical error in SCI publication P419 Brittle fracture: selection of steel sub-grade to BS EN 1993-1-10, within the expression to determine the design crack growth ad presented in section 3.1.1.

The sign of the fourth term in the expression should be negative and read

The typo is repeated in the numerical example in Appendix A section A.2 where the expression is stated again. However, the result of the expression (a design crack depth of 2.26 mm) is correctly stated, having been calculated respecting the correct sign. The tabulated values in the publication have also been determined using the correct expression.
