| Abstract: | The mixed-mode SIF (stress intensity factor) and other fracture parameters, such as additional non-singular terms in the algorithm, for bending specimens with biased straight cracks and 60° inclined edge cracks have been measured using a full-field selected line method, which may simplify calculations and improve data analysis. The modified Westergaard expressions derived from only stress symmetry have been provided to increase the accuracy of measurements and amplify the data analysis region. |
