A thick plate with a semi-elliptical surface crack subjected to remote tens
ion and tension fatigue loading is considered for the analysis, In the pres
ent study the material is assumed to have variable fracture toughness in th
e surface and thickness directions, Material with isotropic fracture toughn
ess is also considered. The developed three dimensional finite element code
which has the capability to handle singularity and evaluate fracture param
eter based on force method is used to characterise the fatigue crack growth
. Parametric study involving various initial crack sizes is carried out and
Foreman's equation is used to predict the crack growth. Various regions vi
z. break, leak before break are obtained. (C) 1999 Elsevier Science Ltd. Al
