Additive Manufactured Specimen
Multiple cracks in an additive manufactured test specimen model
This sample application shows a fatigue crack growth analysis using the remeshing method for a model of an additive manufactured test specimen. The specimen has an irregular external surface. The specimen has been analysed under cyclic end load using a modified Hartman-Schijve crack growth law.
Figures 1 and 2 show stress plots for the uncracked specimen.
Two semi-elliptic surface cracks and one quarter-elliptic corner crack have been inserted into the specimen as starter cracks close to the locations of peak stress. All three initial crack have the same depth and 3:2 aspect ratio.
Animations of the crack growth are shown in Figures 3, 4 and 5.
