| Abstract: | A numerical technique developed by the authors,which can automatically simulate fatigue crack growth for arbitrary planar defects,is briefly described.The technique,based on the three dimensional finite element analysis,employs the Paris law of fatigue crack growth rate and has a capability of regenerating the finite element meshes as the crack grows.The applicability of the technique is demonstrated by modelling several typical engineering defects. |
