Fig. 11. The grips bending function, g grips , is plotted as a function of normalised crack length, a / W , and the grips compliance parameter, L / R 4 . Markers represent values obtained from FE simulations, while the surface represents linear interpolation between the markers.

Table A.1 provide values for the grips bending function, g grips , as a function for di ff erent values of normalised crack length, a / W , and grips compliance parameter, L / R 4 . The table also provides values for the geometrical function of pin-loaded and bending cases, f pin geo and f bend geo , respectively, as a function of a / W (produced using Eq. (2) and (6), respectively).
