| Summary: | Stress intensity factor for an embedded elliptical crack approaching the free surface of a semi-infinite solid and subjected to a linearly varying pressure is presented in a nondimensional form as a function of position around the crack periphery, crack aspect ratio, and crack distance from the free surface. These stress intensity factors are determined numerically using an alternating technique with two solutions. The first solution deals with an elliptical crack subjected to normal loading expressible in a polynominal of x and y. The second solution involves stresses in a half space due to prescribed normal and shear stresses on the surface. Stress intensity factors for an elliptical crack approaching the free surface of a plate subjected to pure bending are then determined. Stress intensity factors for a semi-elliptical surface crack in a plate subjected to pure bending are also estimated for various crack aspect ratios and crack depth to plate thickness ratios |
