The incidence of roughness induced fatigue crack closure has been studied by finite element modelling.
Results show an increasing effect of crack path angle on closure levels with the closure mechanism being strongly dependent on residual plastic strains in the wake rather than global shear displacements of the fracture surfaces.
An analytical expression for the functional dependence of roughness induced closure has been produced which shows reasonable agreement with the finite element results.
