Abstract
The plastic CTOD range, δp, which quantifies crack tip plastic deformation, is used to study fatigue crack propagation instead of the classical ΔK elastic parameter. A da/dN-δp model was defined for the 304L stainless steel. da/dN was obtained experimentally in standard CT specimens while δp was predicted numerically using the finite element method. The numerical models replicated the experimental tests in terms of geometry, material properties...
