| Abstract: | The ligament yielding of a plate with a semi-elliptical surface crack under tension loading is calculated using the Dugdale model. The stress intensity factor for the strip load is obtained using the weight-function method. The necessary crack opening displacement is calculated with an approach proposed by Petroski and Achenbach. |
